Dr V. Divakar Botcha od nedavno radi kao stariji istraživač u Institutu BioSens. Doktorirao je 2016. godine na Indijskom tehnološkom institutu Bombay (IIT Bombay), Indija, u oblasti 2D materijala i poluprovodnih nanokompozita, kao i njihovih optoelektronskih primena. Tokom doktorata razvio je inovativnu tehniku sa jeftinim, energetski efikasnim i skalabilnim metodom za transfer GO/RGO jednoslojnih “listova” sa interfejsa vazduh-voda na čvrste substrate. Postdoktorat je uradio u oblasti naprednih 2D TMD materijala, gde je fabrikovao dosta fotodetektorskih uređaja na Shenzhen univerzitetu, Kina. Takođe je razvio različite fotonske strukture radeći kao stariji naučnik u Photonics centru (čista soba), u Kini nakon postdoktorata. Na poslednjoj navedenoj poziciji bio je odgovoran za litografiju elektronskim snopom (EBL) visoke rezolucije (modeli: EBPG-5150, Raith pioneer Two) i podučavao je studente, istraživače i neke partnerske kompanije u oblasti procesa fabrikacije uređaja kao što su: dizajn uređaja, razvoj, process fabrikacije, sigurnosni protokol, održavanje čistih soba 100 i 5000, itd. Njegova trenutna naučna interesovanja su u oblasti rasta i fabrikacije 2D-baziranih nanouređaja. Pre nego što se pridružio BioSense institutu, takođe je radio kao stariji R&D inženjer u PROGNOMICS Ltd u Ujedinjenom Kraljevstvu, gde je razvio Multiplex FET senzore na bazi grafena za kardio biomarkere i detekciju alergena u mleku. Ima preko 8 godina iskustva u čistim sobama i korišćenja mnogih uređaja za fabrikaciju. Autor je i koautor više od 30 naučnih publikacija i jednog patenta, citiran preko 495 puta sa H-indeksom 13 i i10 indeksom 16. Takođe je urednik i govornik za različite časopise i konferencije.
