Biography:
Dr. Dejan Maletic is currently employed through the Bay Area Environment Research Institute (BAERI), working as a Research Scientist at NASA Ames Research Center, in The Astrophysics & Astrochemistry Laboratory. He is working on several projects at NASA ARC:
-
Calculating pressure broadening parameters for exoplanetary relevant molecules at high temperatures using IR laser absorption measurements, with Dr. Salma Bejaoui and Dr. Farid Salama.
-
Mass spectrometry measurements of species formed in the COSmIC low-temperature and low-pressure plasma setup for (exo)planetary atmospheric applications with Dr. Ella Sciamma-O’Brien and Dr. Farid Salama.
Dejan obtained his B.Sc. degree in 2008, and M.Sc. degree in 2009 at the Faculty of Physical Chemistry at the University of Belgrade, Serbia. The experimental work conducted as part of these degrees was done at the Laboratory for Gaseous Electronics at the Institute of Physics Belgrade, Serbia. He used mass spectrometry and electrical probe measurements to analyze products formed in atmospheric-pressure plasmas.
Dejan obtained his Ph.D. degree in Physics in 2018 at the Faculty of Physics, University of Belgrade, Serbia with the experimental work done at the Laboratory for Gaseous Electronics led by Dr. Zoran Petrovic at the Institute of Physics Belgrade, Serbia. The title of his Ph.D. thesis was “Diagnostics of plasma jets using iCCD imaging and electrical probes, and plasma jet applications on biological samples” under the supervision of Dr. Nevena Puac. For his Ph.D. thesis, he used plasma diagnostic techniques such as iCCD camera for time-resolved imaging of the plasma evolution in time, and electrical probe measurements. He also studied the plasma jet applications on bacteria samples for sterilization purposes.
For his first postdoc at the Institute of Physics in Zagreb, Croatia, under the supervision of Dr. Niksa Krstulovic and Dr. Slobodan Milosevic, Dejan worked on the synthesis of composite nanoparticles generated by pulsed laser deposition (PLD) and laser ablation in liquid (LAL). He also worked on plasma jet diagnostics using laser-induced breakdown spectroscopy (LIBS) and studied plasma-laser interactions.

For his second postdoc, Dejan worked at the NASA - Jet Propulsion Laboratory, Pasadena, CA, USA, under the supervision of Dr. Stojan Madzunkov, Dr. Dragan Nikolic and Dr. Victor Abrahamsson. He worked on the coupling of the SCHAN instrument (Supercritical CO2 and Subcritical H2O Analysis Instrument for In-Situ Detection of Organics and Life) with the QITMS (Quadrupole Ion Trap Mass Spectrometer) using differential vacuum system, ion transport assembly (quadrupoles and orifices) and electrospray ionization (ESI) source for production and analysis of ions from liquid samples.
