Environmental Biogeochemistry Staff

Marie Kurz, Ph.D.

Section Leader Biogeochemistry Department
Assistant Research Professor Biodiversity, Earth and Environmental Science, Drexel University

215-299-1018 | mk3483@drexel.edu

Dr. Kurz an eco-geochemist, is an aqueous geochemist by training with an interest in the interactions between ecology, geochemistry and hydrology in freshwater systems. Her research investigates the geochemical, ecological and hydrologic processes controlling the availability, transport and cycling of solutes in streams, and the reciprocal interactions between these solute dynamics and stream ecosystem functions, such as nutrient uptake and metabolism. Marie started off working in Florida's spring-fed rivers, transitioned to Germany forested streams, and now has moved on to Pennsylvania and the Delaware River watershed. She received a BS from The College of William & Mary in 2007 and a PhD from the University of Florida in 2013.


David Velinsky, Ph.D.

Director and Department Head, Biodiversity, Earth and Environmental Science, Drexel University

215-299-1147 | velinsky@drexel.edu

Dr. Velinsky is a marine biogeochemist with over 20 years experience in marine and freshwater studies related to nutrient cycling, isotope biogeochemistry, and wetland nutrient and metal geochemistry. He started as an organic geochemist studying the transport of organic compounds in estuaries and from atmospheric transport, and shifted to studies of sulfur and selenium geochemistry. He has published studies related to many aspects of biogeochemistry and has a broad range in the cycling of bioactive elements.


Bhanu Paudel, Ph.D.

Ruth Patrick Post Doctorial Scholar, Patrick Center for Environmental Research, Academy of Natural Sciences

215-299-1171 | bp425@drexel.edu

Dr. Paudel is interested in hydrological processes, sediment-water interactions, and trace element cycling in lotic and lentic ecosystems. His current interests include understanding the impact of climate variability on aquatic resources. Bhanu has studied nutrient biogeochemistry at sediment-water interface in Texas and New Jersey estuaries. He also uses statistical modeling technique to understand the roles of environmental parameters in lotic and lentic ecosystem. He received his B.S and M.S in Environmental Science from Tribhuvan University and earned his Ph.D. in Coastal and Marine System Science from Texas A&M University-Corpus Christ.


Mr. Paul Kiry M.A.

Lead Senior Scientist

Paul has over 40 years of experience in all forms of environmental analysis of nutrients and trace metals. He is known as the chemistry guru, and produces the lowest detection limits and is the point person for any chemistry related question.


Paula Zelanko, M.S.

Paula runs the Elemental and Stable Isotope Mass Spectrometry Facilities. Her research interests include trophic and migratory aspects of bird ecology, subfossil food webs, and biogenic carbonates.


Melissa Bross, M.S.

Melissa manages the chemistry and field coordination aspects of the DRWI project. With background in environmental science and geology, she performs nutrient analyses and maintains field electronics.


Tracey Curran, M.S.

Tracey, with degrees in molecular and cell biology and environmental science, provides unmatched laboratory and field experience. Other departments routinely vie for her assistance in the field.
