My passion for science at an early age led me to pursue my career by doing B.Sc Biochemistry at University of Madras. In 2001, I joined this organization as a M.Sc Medical Lab Technology student (affiliated to BITS, Pilani) and was truly overwhelmed to experience first-hand all the sophisticated lab equipment facilitating research within a world renowned eye hospital in Chennai. I was blessed with wonderful teachers who also supported me in transitioning from a student to establishing myself as an independent researcher/ junior scientist in 2004 in the field of vision sciences. During my PhD, I have established in-house protocols to isolate and successfully establish primary retinal endothelial cell and pericyte cultures for the first time in my lab and used these as diabetic retinopathy models for my research. In recent years, I have also successfully developed human umbilical vein endothelial culture and angiogenesis assays in the lab with my mentor, which is now being used extensively in our lab.
Research experience @ Glance: 7 yrs (Post PG) and 11 yrs (Post PhD) as on 31st march 2022
I have been involved in teaching theory and practical’s classes for BSc and MSc students of MLT and optometry from the year 2004.
I am coordinating and conducting hands on summer training and dissertations for PG students from different colleges from Chennai.
From 2016, I have been recognized supervisor and guide in SASTRA UNIVERSITY for Ph.D
I also regularly uptake role as NABL auditor in conducting internal audits for the departments.

|1||Inhibition of Angiogenesis by decreasing copper in endothelium||Bharathidevi SR, Gomathy Iyer, Prof. KN Sulochana||351561||13.4.20||Approved||Looking forward for Industrial collaborations|
|2||A Method of Identifying an Amino Acid that enhances the production of Nitric Oxide||Vidhya S, Bharathidevi SR, Selvi R, Prof. KN Sulochana||323619||24.10.19||Approved||Looking forward for Industrial collaborations|
My research focus is to discover therapeutic targets that can modulate cellular stress, angiogenesis and inflammation in ocular diseases by clinical studies and validate them in cell based models.
Project 1: Our group has identified the antioxidant enzyme paraoxonase to diminish mitochondria dysfunction in retinal cells and modulate cellular stress and inflammation.
Project 2: We have shown copper induces mitochondrial biogenesis by regulating PGC1β and thereby augment the survival of Retinal pigment epithelial cells. Further copper chelation defies the high glucose induced decrease in MFN2 in retinal cells. We have shown the dyshomeostasis of trace elements in AMD subjects.
Project 3: Our team has established that gaseous neuromodulator hydrogen sulfide (H2S) attenuates homocysteine induced inflammation in retinal cells and silencing cystathionine beta symnthase enzyme decreases VEGF levels in RPE cells
First patent is on the “Identification and selecting the amino acid lysine in enhancing the production of nitric oxide” in relevance to wound healing process and endothelial dysfunction
Second patent is on the “Inhibition of angiogenesis by decreasing copper in endothelium” using SiRNA for inhibiting both systemic and ocular angiogenic diseases.
