Dr. Krishan Mistry (Postdoctoral Research Fellow )

Krishan Mistry

Krishan Mistry is an Assistant Professor of Research at UTA. He received his undergraduate degree and PhD at the University of Manchester in 2021. His research is focused on understanding the properties of neutrinos which, may help us elucidate the origins of the universe. His PhD research received the Springer Thesis Award in 2023 where he studied the interaction of neutrinos with matter making the first measurements of the total and differential electron neutrino cross section on argon with the MicroBooNE liquid argon time projection chamber. His current area of research at UTA focuses on the NEXT neutrinoless double beta decay experiment. He constructed the electroluminescence and cathode regions for the NEXT-100 experiment which will begin operation in 2024, leads efforts in using Machine Learning to analyze double beta decay topologies, and works on developing a new fast simulation with detailed physics for gaseous time projection chambers.

Nicholas Kaelan Byrnes (Graduate Student)

Nick Byrnes

Nick Byrnes is a PhD student at University of Texas Arlington studying physics. A recipient of the University of Texas Arlington Presidential Merit Scholarship, he graduated cum laude from the University of Texas Arlington in 2018, majoring in physics and minoring in mathematics though the University’s Honors College. His primary field of study during this time was positron surface spectroscopy. He started his graduate studies working on the advancement of biochemistry techniques to apply to the search for neutrinoless double beta decay through the detection of barium. He was awarded second place at the University of Texas Arlington ACES poster competition for this research. Nick has since moved on to the development of novel gaseous particle detectors, focusing on the creation of a high speed camera-interfaced Time Projection Chamber for the direct observation of particle interactions. Nick is a recipient of the Michael and Wanda Ray Fellowship, University Scholars Endowment, and James L. Horowitz Physics Scholarship.
