CvEM Group

Kedar Narayan, Ph.D.

Senior Scientist, Group Leader

Kedar Narayan is the leader for the CvEM group. He earned a Ph.D. in immunology, and has a research background in chemistry, pathology, and biophysics. Kedar’s work focuses on the use of emerging technologies for cellular imaging. At CvEM, he is responsible for FIB-SEM and array tomography, technology development and for driving collaborative projects that use vEM and correlative imaging approaches to explore cellular mechanisms.

Melissa Mikolai, Ph.D.


Melissa received her Ph.D. in biophysics from Purdue University with a focus on TEM. She specialized in using 3D EM techniques like electron tomography to study the changes to cellular organelles caused by viruses. She also did a post-doc at the NIH where she developed skills in cryo-electron tomography and cryo-FIB SEM. She focuses on the development and implementation of enhanced protocols for correlative imaging and vEM over a range of different resolutions.

Adam Harned

Research Associate

Adam Harned is an electron microscopist with extensive industry and research experience concerning the applications of VP-SEM, FE-SEM and TEM technologies for both biological and materials samples. His main role will be assisting in the collection of FIB-SEM data.

Abhishek Bhardwaj

Research Associate

Abhishek works as a computational research associate with the CvEM group. He is a graduate in Computer Science and his primary responsibilities involve image analysis, visualization and quantitation of microscopy data. He is focused on applications of AI to analyze and derive insights from complex datasets.

Christopher Dell

Research Associate

Chris Dell works as a Research Associate for the CvEM group. Chris earned his BA in Environmental Science with a concentration in Chemistry from Hood College. He develops and executes sample preparation methods and imaging at our microscopes.

Madeline Barry

Post-Bac Research Associate

Madeline Barry is a post-baccalaureate with CVEM. She joins us after receiving her B.S. from the University of Maryland where she majored in Biocomputational Engineering. She will build on her skills in computer science and explore her interests in biotechnology as she develops and deploys image analysis solutions for vEM data.

Thomas Sova


Thomas Sova is a WHK-SIP intern at the CVEM and a student at Middletown High School. He plans to expand on his computer science skills by assisting with vEM segmentation and quantitation.

Sara Patamawenu


Sara Patamawenu is a WHK-SIP intern at CvEM. She attends Urbana High School and is a biomedical science student at the Frederick County Career and Technology Center. She will build on her interest in cellular biology as she assists with the segmentation and quantitation of vEM data.
