Cultured cortical rat neurons on embedded multi -electrode surface to study neuron/axonal growth
and spontaneous emergence of oscillations and synchrony in developing in vitro brain networks.
Imaged developing brain cultures in vitro and extracted connectivity information and used
probabilistic graph models to quantify connectivity. Concurrently, mul ti-site electrical recordings
(akin to EEG) from the network obtained at various stages were analyzed for correlations.
Frequently interacted and collaborated with multi-disciplinary team members to get work done.
Used custom-built matlab based statistical and signal processing techniques to study emergence of
spontaneous oscillations and synchrony in developing neuronal networks .
Developed a disease model (tumor) and quantified the changes associated with the spread of
disease and compared it with normal cells.
Developed computational models of hippocampal regions (CA3, CA1 and DG) to study network
oscillations and synchrony. Involved in the probabilistic modeling of neurotransmitter receptors
(NMDA and AMPA) and assessing network activity for various extracellular ion concentrations.
Mentored undergraduate supervised graduate level students in my lab.
Electrophysiology Intern:
May 2009 –July 2009
(Department of Cell and Molecular Biology, Tulane University)
Trained under the supervision of electrophysiologists in various electrophysiology protocols and
techniques including rig setup, microscopy techniques and pipette preparation among few.
Involved in making ACSF solutions, brain slices, pipette solutions, gigaohm seals and perform
single-cell current-clamp recordings from PVN region and hippocampal CA3 region.
Presented results at the annual LBRN conference at Baton Rouge, Louisiana (2010).
Teaching Assistant:
(Department Chemistry lab, Louisiana Tech University) Feb 2013 to May 2013
Supervised undergraduate level chemistry students with experiments.
Supervised tests, graded papers and assignments.
Research Assistant:
(Center for Biomedical Engineering and Rehabilitation) May 2004 - Feb 2005
Performed psychophysical experiments to detect threshold to short perturbations.
Compared threshold detection of normal with neuropathic patients.
Senior Design Project and related Experience:
Co-developed a cost-effective DSP based audiometer for psychophysically assessing degree of
auditory impairment in patients using ADSP 2181 DSP fixed point processor.
Proposed a piezoelectric based cochlear implant model that could be potentially used as an
auditory prosthetic.
Proposed research plan to estimate the strength of presynaptic neurotransmitter concentrations and
neural anatomical architecture in the strength of memory formation in behaving rodents.
