Assistant Professor, Immunobiology

Michael D. L. Johnson received his bachelors from Duke University. He obtained a Ph.D. in Biochemistry and Biophysics from the University of North Carolina at Chapel Hill, where he studied the effects of calcium on bacterial motility and attachment under the mentorship of Matthew Redinbo. For his postdoctoral training, Michael Johnson went to St. Jude Children’s Research Hospital in order to work with Jason Rosch on metal homeostasis of Streptococcus pneumoniae and subsequently with Douglas Green on the mechanisms of LC3-associated phagocytosis. Michael Johnson joined the faculty of the University of Arizona in 2016.

Graduate Assistant, Research

Sanjay Menghani grew up in Vineland, NJ and received his bachelors from UPenn in biochemistry and economics. During his undergrad years, he spent time working in the lab of Dr. Sara Cherry, a renowned virologist and microbiologist. In her lab, he studied Rift Valley fever virus and innate mechanisms of antiviral defense. After spending a year working at the NIH Clinical Center as a Post baccalaureate IRTA Fellow, he moved to Tucson to begin his MD/PhD training at the University of Arizona. After completing his first 2 years of medical school, Sanjay officially joined the Johnson Lab and is working towards his PhD in Immunobiology. Sanjay is interested in understanding infections from both the host cell and pathogen's perspectives. In the Johnson Lab, he will venture to better understand the role of copper and other metals in the infection process, with the end goal of helping to develop novel therapeutic strategies against bacterial infections that he can bring to the bedside down the road.

Graduate Assistant, Research

Henrik received his Bachelor’s degree in Biology from the University of Utah in 2016. He joined the lab in March of 2018 and is pursuing a PhD in Molecular Medicine – Immunobiology. He is interested in identifying and understanding bacterial pathways utilized in overcoming copper stress. In his spare time, he enjoys hiking, playing board games, and solving puzzles.


Chansorena received her Bachelor’s degree in Biology from the University of Arizona in 2019. She joined the lab in June 2020 as a Master’s student in the Applied Biosciences program. She is interested in identifying novel therapeutics to treat infectious diseases. In her spare time, she enjoys art, exploring new food places, reading, and spending quality time with family and friends. 


Alison Watson received her Bachelor's degree in Biology from Northern Arizona University. In 2019, she joined the Johnson lab as a Post-Baccalaureate Research Education Program (PREP) student at the University of Arizona. Outside of lab, she enjoys traveling, watching Taika Waititi movies, and hanging out with her cat.
