Meet Our Faculty

in this section

At Cornell's School of Civil and Environmental Engineering, faculty and student research is focused on three mission areas of study: Civil Infrastructure, Environment, and Engineering Systems and Management.

 

Environment

Environmental Processes

Damien Helbling


Damian Helbling, Assistant Professor

Helbling’s research is focused on water quality as it relates to human and ecosystem health; in particular, the investigation of chemical and biological processes that influence contaminant fate and nutrient cycling in natural and engineered aquatic systems, with the goal of creating water treatment and resource recovery technologies, mechanistic models for contaminant fate and exposure risk assessment, and comprehensive and sustainable management strategies for urban water systems.

Helbling has taught at Cornell since 2014. He holds a BS in civil engineering with a minor in environmental engineering from The Pennsylvania State University, and an MS and Ph.D. in civil and environmental engineering from Carnegie Mellon University. 

 

  

Len Lion


Leonard Lion, Professor

Lion's research aims to improve the understanding of processes that influence the fate and transport of pollutant compounds in both natural and engineered systems, much of which is related to sustainable water treatment processes. To date, he has investigated toxic trace metal cations and nonionic organic compounds. Lion’s research is often performed in support of Cornell University’s Agua Clara project, an organization working to make safe drinking water accessible to people in developing countries.

Prior to joining the CEE faculty, Lion worked with the U.S. Public Health Service on assignment to the Environmental Protection Agency, Office of Solid Waste Management. He was a resident research fellow with the U.S. Air Force Engineering Services Center. Lion holds both a master’s and doctorate degree from Stanford University.

Matthew Reid joined the Cornell CEE faculty in July 2016. Most recently he has worked as a post-doctoral scientist at the Swiss Federal Institute of Technology in Lausanne, to study microbially-driven arsenic cycling in rice paddy soils.

Reid analyzes the use of engineered and managed ecosystems as sustainable tools for water quality protection;  his research is focused on the coupled biological, chemical and physical processes that govern contaminant fate in soils, and on how these natural processes can be harnessed to preserve water quality and reduce greenhouse gas emissions from nutrient cycling. Reid holds a Ph.D. in civil and environmental engineering from Princeton University and a BA in chemistry from the University of Chicago.

 

 

Ruth Richardson


Ruth Richardson, Associate Professor

Richardson’s research group studies the myriad activities of microbial communities through the application of molecular biological techniques with the overall goal of discovering key molecular biomarkers of specific metabolic processes and relating quantities of such biomarkers with rates of reactions and/or bioreactor stability. Some current research projects are in the areas of groundwater bioremediation (especially chlorinated solvents and uranium), bioenergy, greenhouse gas cycling, and wastewater treatment. Richardson joined the faculty in January 2002, after completing her MS and Ph.D. in civil and environmental engineering at the University of California at Berkeley. Richardson also holds a BS in chemical engineering from Manhattan College.

 

 


Environmental Fluid Mechanics & Hydrology

He has developed experimental techniques, built new facilities, and undertaken basic research in several areas of expertise. Cowen's overarching philosophy is to develop a curriculum that instills a fundamental foundation in the material but ultimately looks at the application of the material to real-world problems. This goal permeates his lecturers, the problem sets he assigns, and his exams.

Cowen joined the Cornell faculty in November 1997. He holds a BS in civil engineering form Brown University and an MS/Ph.D. from Stanford University.

 

 

Peter Diamessis - weighted


Peter Diamessis, Associate Professor

Diamessis' research at Cornell is focused along two main themes: One is the development of high-accuracy and high-resolution spectral quadrilateral subdomain penalty techniques for the incompressible Navier-Stokes equations which enable as realistic as possible an approximation to the environmental flow processes of interest; the other consists of using these techniques as the driver of highly parallel simulations which provide an accurate description of the relevant physical phenomena (namely the interplay between turbulence and internal gravity waves in stratified flows) over as broad a range and separation of scales and as long a duration as possible.

Diamessis joined the CEE faculty in January 2006. He received his undergraduate degree in Mechanical Engineering from the National Technical University of Athens (NTUA), Greece in 1995. From 1996 to 2001, he pursued graduate studies at the Mechanical and Aerospace Department of the University of California, San Diego.
