A potentiostat is a voltage source that is able to vary its output potential in response to changes in the resistance across a circuit. In electrochemistry experiments, potentiostats are able to supply more or less current so that the potential across an electrochemically active cell remains constant as per Ohm’s Law. Electrochemical techniques like cyclic voltammetry, linear sweep voltammetry, and other types of voltammetry require a potentiostat to measure redox events taking place in a solution. The Autolab potentiostat/galvanostat instrument is state of the art instrumentation that can be used for virtually all electrochemical applications.

Background
Joined GSFC University in July 2019
Scholarship and Accomplishments
Dr. Poonam Sharma worked as research scholar under research project entitled, “Development of Zr and Ni - based metallic glasses and Surface modification for reprocessing applications” from BRNS/ Department of Atomic Energy, Govt. Of India. Dr. Sharma has mainly focused on the corrosion properties of Zr-based bulk amorphous alloys which shows high corrosion resistance in nitric acid medium. She has carried out her research work at Indira Gandhi Center for Atomic Research, Kalpakkam, Tamilnadu” under the guidance of Dr. Kamachi Mudali in collaboration of BRNS/DAE Research Project. She has also worked on bulk metallic glass casting system and casted Zr-Cu-Ni-Al bulk metallic glasses which were further used for corrosion investigation in nitric acid medium. Dr. Sharma also performed Oxygen and Nitrogen ion implantation studies at IGCAR Kalpakkam.
Dr. Sharma has a teaching experience of more than 07 years. Previously she has served as an assistant professor at Jaipur national university, Jaipur for 01 year and at AnandICE, Jaipur Rajasthan for 03 years. She is working as an assistant professor, physics at GSFC University since July 2019. She teaches physics to science students at B.Sc. and B.Tech. Program. Also Dr. Sharma teaches corrosion science subject to chemical engineering students. She exposes students to science fundamentals and has chosen teaching to conduct research in education. Dr. Sharma was a supervisor of 7 M.Sc. Student for M.Sc. Dissertation. Students have studied the effect of Banyan Tree Leaf Extract on Corrosion behavior of Mild steel in HCl, HNO3, H2SO4 and NH3 medium.
Dr. Poonam Sharma is also a Start-up coordinator of School of Science under GSFC University lnnovation lncubation Technology Applied Research Centre (GUIITAR) Council. She has mentored one project “water trace collector” funded under student startup and innovation policy (SSIP), Gujarat. Dr. Sharma is also a Life member of Society for Advancement of Electrochemical Science & Technology (SAEST) Karaikudi, Tamilnadu.
