The OPA Board of Directors is an elected, volunteer group consisting of executive members and committee chairs.

We meet once a month to discuss various updates and needs related to our mission. All meetings are open to the postdoctoral community. Please email us for more information on the meeting schedule!

Our 2020 Board members are:


Priyadarshini Chakrabarti (Basu), Ph.D., Research Associate (Post Doc), College of Agriculture Science. "I am an entomologist working on honey bee nutrition, impacts of pesticides on honey bees and honey bee behavior and biology. I work on research related to pollination, insect nutrition, molecular ecology, neuroethology, insect ecotoxicology, insect physiology, chemical ecology etc. I am also interested in extending my expertise to studying pests."

Vice President

James Fox, Ph.D., Research Associate (Post Doc), Department of Microbiology. "My research investigates how the physiology and composition of marine plankton communities are linked to variability in carbon export efficiencies.  Through ship-based observations and experimental approaches, my work will (i) shed light on how bulk photic layer plankton properties can be linked to optical properties retrievable from remote sensing and (ii) explore the potential of active sensor-based technologies."


Kelsey L. Søndreli, Ph.D., Research Associate (Postdoc), Department of Botany and Plant Pathology. The main focus of my research is understanding host-pathogen interactions in forest ecosystems. I am currently working with the Sphaerulina musiva - Populus pathosystem as well as researching tanoak resistance to Sudden Oak Death caused by the pathogen, Phytophthora ramorum


Nicolas Martin, Ph.D., Postdoctoral Scholar, Department of Chemistry.
I obtained my Ph.D. from University of Lille, France before joining OSU in 2018.
My research focuses on niobium chemistry and crystallography. My role is to synthesize new niobium oxo-clusters and to study their interactions with other metals in both solution and solid state. 

Professional Development Coordinator

Dorukhan Ardağ, Ph.D., Postdoctoral Scholar, College of Earth, Ocean, and Atmospheric Sciences.

I obtained my Ph.D. from the University of Florida in Coastal and Oceanographic Engineering with a focus in wave physics and modeling. My main research at OSU involves using oceanographic measurements obtained via tagged cormorant birds and comparing this biologging derived data with results from a high-resolution coupled wave-current ocean model. This data will also be used for data assimilation in cases with uncertain model parameters.

I received my B.S. from Boğaziçi University in Istanbul, Turkey and M.S. from the University of North Florida in Jacksonville, Florida.

Industry Exploration Program Coordinator

Radwan Elzein, Ph.D., is a Postdoctoral Scholar at the School of Chemical, Biological, and Environmental Engineering. His current research interest related to surface electronics/chemistry of materials’ system which have impact on molecular electronic devices.

He studied Nanotechnology and Nanoelectronic Devices at University of Surrey and worked at Merck, UK prior to receiving his Ph.D. in Electrical Engineering from University of South Florida, USA, where he conducted research related to physical electronic properties of 2D and 3D SURMOF thin films.

Membership Coordinator

Xi Zhang, Ph.D., Postdoctoral Scholar, College of Earth, Ocean, and Atmospheric Sciences. Broadly, Xi’s research interests include: hydrologic processes in the vadose zone, soil water dynamics at different spatial and temporal scales, and climate-induced changes in soil structure and subsurface flow paths. Xi received Ph.D. in Soil Science from the University of Kentucky and M.S. in Environmental Engineering from Zhejiang University (China).

Networking and Social Events Coordinator

Mareike Möller, Ph.D., Postdoctoral Fellow (DFG Research Fellowship), Department of Biochemistry and Biophysics.
I obtained my PhD from the University of Kiel and the Max Planck Institute for Evolutionary Biology, Germany, in 2018 and joined the OSU in September 2019. 

My research focuses on chromatin biology and genome stability in filamentous fungi. I am especially interested in how chromatin conformation impacts nuclear localization and DNA damage responses.  


Web administrator and Public Relations Coordinator

Sampath Adusumilli, Ph.D., Post-Doctoral Scholar, MIME department

I obtained my Ph.D. from Georgia institute of Technology in Aerospace Engineering. My research focused on understanding the combustion chemistry of aviation fuels at aircraft engine operating conditions. At OSU I aim to apply the knowledge of combustion to study wildfire propagation. To achieve this, I study tree scale burning with intention of enumerating firebrand/ember generation rates for different tree species.
