Sanjna Banerjee

Sanjna received her bachelors and masters from degree from VIT University, Vellore in Biotechnology. Initially a student of molecular neuroscience, she was inducted into the intriguing field of systems neuroscience as a graduate student in the cognition lab. She is trying to understand certain questions about visuospatial attention and it’s components by tying TMS techniques with behavioural experiments. She enjoys reading fiction.

Sriram Rajkumar

Sriram has completed his in biotechnology from Jeppiaar Engineering College, Chennai. The question of ‘how do we think’ that persisted in him since those undergraduate years drove him to begin his foray into neuroscience by working on spatial working memory for his UG project . He is a graduate student in the lab, and is currently working on target distracter interaction in attention using Electroencephalography. He is an avid nature lover and traveller.

Arshed Nabeel

Arshed completed his Masters in Computer Science from CSA, IISc; and Bachelors in Computer Science from University of Kerala, Trivandrum. He is a graduate student in the lab, jointly with Department of Computer Science and Automation and Centre for Neuroscience. He is broadly interested in theoretical computer science, mathematics and scientific data analysis, and how these three fields can cross-pollinate. His research aims to understand how the parts of the brain interact to form a greater whole by using a variety of analytic and algorithmic techniques. Apart from science, he enjoys all things design.

Varsha Sreenivasan

Neuroscience and Mathematics are two fields that have fascinated Varsha since high school. She obtained her Bachelors degree from St. Xavier's College, Mumbai as a Math major and her Masters in Mathematics from the Indian Institute of Technology, Madras. She started her tryst with computational biology at the Institute of Mathematical Sciences (IMSc) Chennai, as Project Assistant. She is a graduate student in the lab, trying to quantify the structural connectivity in the brain using diffusion MRI and how this correlates with functional interactions among brain regions. Her other interests include listening to music, indulging in gourmet food and occasional retail therapy sessions.

G V K Madhav

Madhav’s broad area of work is neuronal dynamics. He has a degree in Mathematics and is presently being trained in Computational Science from IISc for his master’s degree, working in the cognition lab towards his project. He is trying to understand why the brain is restless even at rest, with the help of Mathematical Equations and snapshots of the brain taken using different techniques like fMRI .

Simran Purokayastha

Simran enjoys exploring how cognition and conscious processing work in 'normal', 'gifted' and 'clinical' populations. She has a bachelors in Psychology from Christ University, Bangalore and an MSc in Human Cognitive Neuropsychology from the University of Edinburgh. She has led the eyetracking project studying attention through change blindness. She is currently working on a department-wide project to identify early biomarkers of Alzheimer's Disease using multimodal imaging. She loves writing précis pieces, reading, or trekking.

Abhimanyu Pavluri

Abhimanyu obtained his bachelors and masters in mechanical engineering from IIT Kharagpur. In his final year he witnessed a Parkinson’s patient’s recovery after being implanted with DBS, and this encouraged him to explore the fascinating realm of neuroscience. His research interests include Neural engineering and theoretical neuroscience. He is currently working on group inference of Alzheimer patients with Dynamic causal modelling. Besides research, he is interested in bikes, travel and food.

Shrey Grover

Shrey did his bachelors in Mechanical Engineering from BITS Pilani Goa Campus. A course on Psychology (and a fascination for the etymology of terms like corpus callosum, genu and septum pellucidum) was his initial push to explore the science behind our brain and behaviour more sincerely. He is involved in characterising perceptual and decision-making components of attention using psychophysics experiments, and TMS. Shrey likes the idea of travelling and is waiting for the opportune moment for a world tour.

Mali Sundaresan

Mali’s interests lie in applied mathematics, machine learning and computational neuroscience. His previous avatars include an electrical engineering undergraduate at IIT Madras and a Prog-Analyst at Citibank. He is working on functional connectivity of brain regions, using fMRI data. When not working, you’ll find him watching Arsenal falling short in the Premier League title race yet again.
