After his Ph.D. in Neuro-informatics in 2015, Dr. Jac joined as a Project Associate in the same Lab under Dr. S. Ramakrishnan and was in charge for the projects in different fields including Brain imaging and EMG processing. He served in organizational committee for the conferences hosted by the lab during this tenure. He obtained skills in planning in vitro and in vivo experiments, statistical analysis, writing grant proposals, articles, patents, and working in an interdisciplinary team. Later, Dr. Jac joined as an Assistant Professor (Senior Grade) in 2016 at VIT University, Vellore, India and delivered courses on Bio-Medical Instrumentation, Sensors, Medical Physics and Rstudio for students. Further, Dr. Jac supervised three undergraduate projects, which have improved his skills in mentoring and support in career objectives. He undergone research in VAG signals, developed machine learning model for the diagnosis of articular diseases and published the outcome in a journal. Further, he developed a process pipeline to identify the damages in composite materials using digital images and published in 4 leading journals sooner and later. Dr. Jac was funded grant by Indo-Us Science and Technology Forum/ Science Engineering Research Board, India to pursue Post-Doctoral studies under Prof. Ralph Axel Mueller at Brain Development Imaging Lab, San Diego State University, USA in 2016. This group is pioneer in autism spectrum disorder research using behavioural, clinical measures, multi-model imaging modalities like sMRI, fMRI, DTI and EEG. He worked in two projects including machine learning models for autism using resting-state fMRI and identification of subtypes in autism using multi-model imaging methods. During this tenure, Dr. Jac was trained in resting-state fMRI processing, DTI processing and training in brain imaging tool boxes like FSL, AFNI, Freesurfer, coding in bash script and working on High Performance Computing through remote server. Based on his studies, Dr. Jac has published two papers (1 journal and 1 conference) related to machine learning models for autism. In 2018, Dr. Jac joined as a Research Fellow in Nanyang Technological University, Singapore under the supervision of Prof. Justin Dauwels. The lab is pioneer in developing advanced brain connectivity estimation methods and machine learning algorithms in application to brain development research. He got opportunity to work in brain connectivity analysis methods in collaboration with Prof. Georg Langs, Medical University of Vienna, Austria. The outcomes of this research study are published in a journal and a conference poster. During this tenure, Dr. Jac acquired a strong background in neuro-informatics (brain network connectivity estimation methods), machine learning (deep learning), high complexity algorithms, and coding platforms like python.
In the mid of 2020, Dr. Jac got Advanced Research Opportunities (AROP) Scholarship to wok under Dr. Kerstin Konrad, Clinics & Institute, Clinic for Psychiatry, Psychosomatic, and Psychotherapy of childhood and adolescents in RWTH Aachen, Germany. This group work in autism traits, neural mechanism, child development, gender variation, behavioural dimensions, neuroimaging, functional brain connectivity, and diagnostic classification of neuro developmental disorders. Recently, Dr. Jac joined as an Assistant Professor in the School of Bio-Medical Engineering in IIT (BHU), Varanasi, India.
