Research Description By Graduate Engineering Department

Applied Physics & Applied Mathematics

The Department of Applied Physics and Applied Mathematics includes undergraduate and graduate research in the fields of applied physics, applied mathematics, and materials science and engineering.

The graduate program in applied physics includes research in plasma physics and controlled fusion; solid-state physics; optical and laser physics; medical physics; atmospheric, oceanic, and earth physics; and applied mathematics.

Biomedical Engineering

Mirroring our undergraduate and graduate curriculum, our research areas are generally associated with three research tracks: biomechanics, cell and tissue engineering, and biomedical imaging. However, it is in the overlap between these broad and diverse areas that our true strength lies.


Cell and tissue engineering includes the study of cellular mechanics and cell signaling, mechanotransduction, biosystems engineering and computational biology, nanotechnology, microfluidics, bioMEMS and gene chips, functional tissue engineering and biomaterials, tissue structure-function and cell-matrix interactions.

Biomedical imaging encompasses biophysics of image formation from molecules to tissues, signal detection and formation, image and signal processing using quantitative analysis, modeling the physical and biological processes, and performance evaluation. Specialty areas include MRI, ultrasound, biophotonics, microscopy, EEG, and medical imaging processing.

Biomechanics includes the topics of musculoskeletal mechanics, cardiac mechanics, mechano-electrochemical responses of soft and hard tissues, cell-matrix interactions, cellular biomechanics, functional tissue engineering, image-based functional anatomy, and computer-assisted surgery and surgical planning. See here for individual labs.

Where these fields intersect, we have established particular expertise and resources dedicated to a growing number of research fields including:

Cardiac research: Cardiac biomechanics, cardiac tissue engineering and state-of-the-art in vivo cardiac imaging.
Neuroengineering: Computational modeling of neural systems, in vivo clinical and pre-clinical neuroimaging, neurotrauma and repair research, neuronal tissue engineering.
Stem cell research: Functional tissue engineering and regenerative medicine research using stem cells.

Microscale engineering and nanotechnology: Cell positioning and molecular design, MEMs and lab-on-a-chip diagnostic devices, micro- and nano-fabrication techniques combined with advanced microscopy.
Orthopedics research: Musculoskeletal biomechanics, cellular and molecular bone biomechanics, bone and tissue interface tissue engineering, in vivo imaging of osteoarthritis.

Chemical Engineering

Molecular Design and Modification of Material Surfaces:
There is much current interest in developing polymer surfaces that are adaptive and responsive to various stimuli. The goal of this research is to create surface-active polymers that deliver various photoactive functional groups and polymers to the surface.

Biophysics and Soft Matter Physics:
Soft matter denotes polymers, gels, self-assembled surfactant structures, colloidal suspensions, and many other complex fluids. These are strongly fluctuating, floppy, fluidlike materials that can nonetheless exhibit diverse phases with remarkable long-range order. In the last few decades, statistical physics has achieved a sound understanding of the scaling and universality characterizing large length scale properties of much synthetic soft condensed matter. More recently, ideas and techniques from soft condensed matter physics have been applied to biological soft matter such as DNA, RNA, proteins, cell membrane surfactant assemblies, actin and tubulin structures, and many others.

Genomics Engineering:
Genomic research is focused in five areas: human disease mapping, bioinformatics approaches to enhancing disease gene discovery, improvement in the chemistry and engineering of genomic technologies, whole genome sequencing and characterization, and post-genomic technologies.

Interfacial Engineering and Electrochemistry:
We are interested in a large number of problems that are often characterized as belonging to "electrochemical engineering" as well as the emerging field of microfludics. Applications in electrochemical engineering include electrochemical metallization processes, corrosion, fuel cells, batteries, and waste-treatment processes. Applications in the area of microfluidics include sensors and "labs on a chip." Research efforts are focused mainly on basic issues concerning the design and control of electrochemical systems. A particular application involves studies of both feature and wafer scale phenomena in the copper metallization process that has been introduced into the computer industry for advanced, on-chip interconnects.

Protein and Metabolic Engineering
Research in protein engineering involves the enhancement of proteins and peptides for the improvement of specific applications using a variety of molecular biology tools and techniques. Metabolic Engineering refers to the modeling and improvement of networks of enzymes that function together in a metabolic pathway.

Earth and Environmental Engineering

Research at EEE lies at the intersection of scientific advancement, technological innovation, and environmental problem solving. A sampling of current research projects is provided here, grouped according to our three thematic concentration areas:

Environmental Health Engineering focuses on identifying, evaluating, and rectifying environmental problems that have a discernable impact on public health. The central idea is that many threats to human health are related to the environment, and the most effective way to alleviate the threat is to prevent or remediate the underlying environmental problem. Projects following this theme strive to pinpoint the environmental causes of disease occurence, and develop engineering solutions to these causal factors.


Sustainable Energy and Materials focuses on innovative ways to provide energy and material resources to society, in a sustainable and environmentally responsible manner. The central task is to build and shape the energy and industrial infrastructure of the 21st century. Many projects focus on treating the inefficiencies and by-products of traditional production in novel ways, such as carbon sequestration, zero-emission coal, catalysis, and recycling technologies. Other projects focus on developing viable alternative energy sources, such as waste-to-energy.


Water Resources and Climate Risks focuses on the movement, availability, and quality of water throughout the Earth, on scales ranging from individual rivers and watersheds to the entire globe. Providing this valuable resource for society is the overarching goal, and the risks posed by climate variability, extremes, and change is an important and inherent part of all research projects. Specific projects range from the management of available supplies to forecasting future availability to underlying scientific mechanisms, and span a number of disciplines such as hydrology, hydroclimatology, water resources engineering, atmospheric dynamics, and land-atmosphere interaction.

Electrical Engineering

Information on research being done by the Electrical Engineering Department can be accessed through five general categories:

•Signal and Information Processing

Center for Computational Learning Systems

Businesses, institutions and individuals are generating and collecting data at an astonishing rate, growing faster than our ability to understand it, predict patterns or results, or use the information to achieve needed outcomes. The Center for Computational Learning can harness this data for greater human understanding as well as for very specific business applications. To do this, our world-class researchers in machine learning and data mining, focus on the specific goals and challenges of our clients, including private and public companies, medical centers, public utilities, government agencies and academic institutions.

The Center’s projects have focused on a wide-range of challenges in such areas as energy and public utilities, medical and biological research, systems and tools for translating languages and dialects, human learning and cognition, machine learning, and security systems. Although focusing on different types of challenges, all CCLS projects share a common goal: to understand, predict and produce the outcomes needed by each client. CCLS research scientists working in all project areas analyze massive amounts of data by research scientists using computational machines that organize data to “learn” about patterns, causes and predictability, i.e. “machine learning.”

Center for Financial Engineering

The Center for Financial Engineering was established at Columbia University with the goal of encouraging interdisciplinary research on financial engineering and mathematical modeling in finance and promoting collaboration between Columbia faculty and financial institutions, through the organization of research seminars, workshops and the dissemination of research done by members of the Center.

Center for Integrated Science and Engineering

The Center presently supports multi-disciplinary research in the Departments of Applied Physics, Chemical Engineering, Chemistry, Electrical Engineering and Physics.

Center for Life Cycle Analysis

The Center for Life Cycle Analysis (LCA) of Columbia University was formed in the spring of 2006 with the objective of conducting comprehensive LCAs of energy systems. LCA provides a framework for quantifying the potential environmental impacts of material and energy inputs and outputs of a process or product from "cradle to grave". The mission of the Center is to guide technology and energy policy decisions with data-based, well balanced and transparent descriptions of the environmental profiles of energy systems.

Center for Neuroengineering and Computation

The Columbia Nanocenter is motivated by two key propositions. The first proposition is that theminiaturization of silicon-based electronics will stagnate in the early part of the 21st century. The second proposition is that the desire for exponential improvement of device performance (as measured by clock speed, circuit density, computing power in mips, etc.) - that is, Moore's Law - will extend into the foreseeable future. Our program is directed toward the expectation that individual molecules provide an attractive alternative to silicon circuitry for carrying out logical operations. Thus we seek to establish the foundation for new paradigms for information processing through the development of fundamental understanding of charge transport phenomena unique to the character of nanoscale molecular structures. Beyond electronics applications, the fundamental studies of molecular transport in the Columbia Nanocenter have the potential to impact other disciplines such as photonics, biology, neuroscience, and medicine.

Center for Particulate and Surfactant Systems

Particulate and surfactants systems are vital to virtually every major industry including pharmaceuticals, detergents, cosmetics, liquid crystals, micro-electronics, advanced materials, energy, minerals, biotechnology, photography, and paints and coatings. Most applications involve the use of dry or wet particulate systems and natural or synthetic surfactants whose effectiveness depends on the synergistic or competitive interactions with each other. Better understanding of the interplay between particles and surfactants will lead to products and processes such as better detergents, faster acting drugs, multimodal contrast agents for early disease detection, and advanced separation technologies.

CPaSS faculty, staff and students are currently conducting, or plan to undertake, research projects in the following areas that have been identified by the Center researchers and industry partners.

•Cosmetics and Health care Products

Columbia Center for Integrated Science and Engineering

One focus of MRSEC research is in developing novel ways of making nanocrystals, particularly metal oxide nanocrystals. We are pursuing new ways of synthesizing different types of particles by colloidal methods, such as iron oxide nanoparticles (gamma-Fe2O3, TEM figure 1) and HfZrO2 nanoparticles and nanorods (figure 2). We are also investigating the synthesis of CeO2-y and ternary nanocrystals such as CeZrO2 by room temperature liquid phase methods, and of vanadium oxide nanorwires by hydrothermal methods (figure 3). The synthesis of iron oxide nanocrystals was a collaboration with Chris Murray of the IBM T.J. Watson Research Center (currently at the University of Pennsylvania). The TEM in figure 2 is the result of a collaboration with Yimei Zhu at Brookhaven National Laboratory.

Columbia Networking Research Center

Organic and hybrid materials offer potential for low cost, large area, manufacturable solar-cells. Although there are multiple problems associated with these material systems, for example stability and lifetime, the primary issue at this point in time is that they simply have not offered operating efficiencies at an acceptable level. The Columbia EFRC is founded on the belief that improving photovoltaic efficiency for these systems requires fundamental and quantitative understanding of the energy flow through the system from the light absorption process to the power delivery process. The EFRC will focus on using the tools of nanotechnology and ultrafast science to achieve a deeper understanding of the fundamental efficiency limits of organic and hybrid solar cells at each step in the energy conversion cascade. We will apply this knowledge to the design and implementation of new, high efficiency solar-cell systems. Building from this understanding, we will explore material design for the creation of innovative and scalable architectures tailored to optimize charge extraction and transport. Furthermore, single junction organic and hybrid solar-cell systems are subject to the Shockley-Queisser (SQ) limitations for conversion efficiency. Many concepts for going beyond SQ have been proposed, but very little success has been reported so far for organic and hybrid systems. In particular the concept of carrier multiplication or multi-exciton generation (MEG) is attractive, but a deeper understanding of these processes is required to evaluate the potential for this concept. Thus our research program will examine extensively these concepts both theoretically and experimentally based on optimized nanomaterials created through cutting-edge synthesis capability

Computational Optimization Research Center

CORC researchers carry out advanced studies in the solution of difficult, large-scale optimization problems, with special focus on state-of-the-art implementation of modern algorithms. We are primarily interested in the solution of problems with practical relevance, and we actively seek collaboration with industrial partners.

Data Science Institute

The Data Science Institute at Columbia University is training the next generation of data scientists and developing innovative technology to serve society. With nearly 200-affilated faculty working in a wide range of disciplines, the Institute seeks to foster collaboration in advancing techniques to gather and interpret data, and to address the urgent problems facing society. The Institute works closely with industry to bring promising ideas to market.

Earth Engineering Center

The Earth Engineering Center (EEC) was formed in 1995 by the Earth Institute, the School of Applied Science and Engineering (SEAS), and the Henry Krumb School of Mines of Columbia University. Its original mission was to direct engineering research on processes and products that balance the increasing use of materials, the finite resources of the Earth, and the need for clean water, soil, and air. The Center was also dedicated to the advancement of industrial ecology: The physical and social sciences for reconfiguring industrial and societal activities with full knowledge of their environmental consequences. EEC introduced the teaching of Industrial Ecology of Earth Resources at Columbia University, was the first engineering unit of Columbia's Earth Institute, and co-organized the 1997 Global Warming International Conference (GW8), held at Columbia University.

The EEC has concentrated on advancing the goals of sustainable waste management in the U.S. and globally. Economic development has resulted in the annual generation of billions of tons of used materials which are a considerable resource and, when not managed properly, constitute a major environmental problem both in developed and developing nations. This research has engaged many M.S. and Ph.D. students on all aspects of waste management.
