Babak N. Safa, Ph.D.

babakn (at) usf.edu - Office enb 139

Dr. Safa is an Assistant Professor of Medical Engineering at the University of South Florida, leading innovative research in soft tissue biomechanics with a focus on glaucoma. His current areas of focus are iris biomechanics and optic nerve head remodeling, addressing both angle-closure and open-angle glaucoma. Prior to joining USF, Babak was a BrightFocus Postdoctoral Fellow at Wallace H. Coulter Department of Biomedical Engineering at Georgia Institute of Technology and Emory University at Prof. Ross Ethier's lab, where he investigated glaucoma biomechanics and mechanobiology. Dr. Safa earned his Ph.D. from the University of Delaware, and his thesis was focused on tendon damage mechanics at Prof. Dawn Elliott's lab, and his Bachelor of Science in Mechanical Engineering from Sharif University of Technology, Iran's premier engineering university. Through his research, Dr. Safa aims to advance our understanding of ocular biomechanics and develop novel approaches to combat visual impairment.

Babak is a professional musician, and he plays Qopuz (an Azerbaijani string instrument), watch Babak on stage. Also, he was a member of Iran’s national astronomy olympiads team, and he won a bronze medal at the international astronomy and astrophysics olympiads in Thailand (IOAA 2007).

Postdoctoral fellows

Postdoctoral fellow

Ananya Naha, Ph.D.

anaha (at) usf.edu

Ananya is a post doc researcher at the Safa lab, University of South Florida. She earned her doctoral degree from Florida State University under the supervision of Dr Tristan Driscoll in 2025 where she studied the role of integrin extracellular matrices in activation of fibrotic, inflammatory pathways and mechanosensing in the nucleus pulposus cells of the intervertebral discs. She obtained her master’s degree in biotechnology from Birla Institute of Technology, Mesra India where she focused on design of experiments for levodopa production for Parkinson’s disease. She also did her bachelor's in biotechnology from Haldia Institute of Technology where she studied the effects of ZnO nanoparticles in diabetic and non-diabetic patients.

Ananya is a trained Hindustani classical singer. She enjoys going on trips and reading books.

Graduate Investigators

doctoral student IN BIOMEDICAL ENGINEERING

Nima Rafezi, M.Sc.

nrafezi (at) usf.edu

Nima is a doctoral student in the Biomedical Engineering Ph.D. program at Safa Lab. He has extensive expertise in computer simulations and numerical research methods. In his research, Nima leverages his knowledge of the finite element method to investigate the pathophysiology of angle-closure glaucoma. While working as a research and development engineer in the German automotive industry for multiple years, Nima developed a solid foundation in research-oriented problem-solving as well as strong communication skills. He earned a master’s degree in Computational Mechanics from the University of Duisburg-Essen in Germany and a B.Sc. in Mechanical Engineering from Tabriz Azad University.

Nima is a flamenco music enthusiast. In his free time, he is dedicated to playing guitar and reading books.

doctoral student IN BIOMEDICAL ENGINEERING

Krishna Chinmai Dongar, M.Sc.

kdongar (at) usf.edu

Krishna Chinmai is a doctoral student in the Biomedical Engineering Ph.D. Program at Safa Lab, University of South Florida. Her current research focuses investigating primary angle-closure glaucoma using mechanical testing, optical coherence tomography (OCT), and finite element modeling in both humans and animals. Prior to joining USF, Krishna received her B.Sc. and M.Sc. in Biomedical Engineering from the University of Connecticut with a strong background in electronics and systems, mechanical design, and medical device development. Her technical proficiency includes 3D modeling, finite element analysis and experience working in regulatory environments. From her previous internship and academic experiences, she brings in strong research and problem-solving skills. 

Krishna is a professional Carnatic Vocalist. She enjoys music and passionately spreads her enthusiasm for music to the next generations. 

Special Roles

Chief morale officeR

Sevil Safa, RCR

Meet Sevil, our Chief Morale Officer! Once a lightning-fast national sprinter from the great state of Alabama, she gracefully retired in 2020 with her hard-earned RCR (Retired Canine Runner) status. Now, she's embraced her true calling as the ultimate couch potato, offering unmatched expertise in relaxation and spreading kindness. Sevil’s free spirit radiates through the lab, bringing joy and balance to our scientific hustle. Every now and then, she takes on the role of a wise consultant, suggesting to lab members that maybe, just maybe, science could be simplified—preferably while curled up on a comfy pillow!
