Vinaya Basavarajappa received his Ph.D. from the Indian Institute of Science, India. During his PhD, he worked on the development of an improved transdermal drug delivery system using microneedle and micropump technology. For his PhD work, he received the best PhD thesis award from the Institute for Smart Structures and Systems (ISSS), India. In 2015 December, he joined Cornell University, USA as a Postdoctoral Associate to work on miniature ion accelerators using the MEMS approach. During the same time, he explored the pyroelectric research line and demonstrated the pyroelectric ionization source for ion mobility mass spectrometer. In July 2018, he joined INL, Portugal has a Staff Researcher. Currently, his research focus on developing a multi-gas detection platform, print head technology for an inkjet printer, electret-based energy harvester, sensors, and 3-D printed microneedle. His research work appeared in >25 international journals and conference proceedings. Also, he is an inventor of three patent applications (two USA patents and one Indian patent). He also serves as an active peer reviewer and editorial member of several international journals and IEEE conference series.
