Zheng Hu

Project Scientist

My research interest focuses on innovative and unbiased systems biology approaches, such as genomic, epigenomic and epi-transcriptomic analysis, in order to identify the novel regulators and pathways involved in mitochondrial stress signaling and aging in yeast, mammalian and human cells.
Postdoctoral Fellows
Liz Gallagher-sm

Liz Gallagher

Postdoctoral Fellow

I received my PhD in Cell and Molecular Biology at the University of Pennsylvania, working in the lab of Erika Holzbaur. During my graduate studies, I investigated mechanisms regulating the selective autophagy of dysfunctional lysosomes, which critically maintain cellular homeostasis during infection and neurodegenerative disease. Following my interest in cellular quality control mechanisms, I joined the Shadel lab where I am interested in the regulation of mitochondrial nucleic acid release and the associated consequences for cellular homeostasis in specialized cell types.
Sagnika-Ghosh-767

Sagnika Ghosh

POSTDOCTORAL FELLOW

I received my PhD in Vishal Gohil’s lab at Texas A&M University, where I studied how mitochondrial membrane lipids impact mitochondrial membrane protein function and bioenergetics and its implications in Barth syndrome, an inherited disorder of lipid metabolism. Following my interest in mitochondrial biology, I joined the Shadel lab, where I am currently exploring how mitochondria shape host-pathogen interactions in infectious diseases.

Allison Louie

Postdoctoral Fellow

I received my Ph.D. in Neuroscience from the University of Illinois at Urbana-Champaign where I studied how environmental factors such as diet and respiratory viral infection alter oligodendrocyte homeostasis and myelination processes. I joined Salk in 2024 as a joint postdoctoral fellow in the Shadel and Metallo Labs to investigate how mitochondrial dynamics and lipid metabolism of glia are altered during neurological disease.
Kalash_Chandra_Mangalhara-767

Kailash Chandra Mangalhara

Senior Research Associate

I received my Ph.D. from Jawaharlal Nehru University, India with a focus on understanding the role of microRNAs in cancer. In the Shadel Lab, I am working on mitochondria-to-nucleus signaling pathways and the role of mitochondrial metabolism in tumor growth, immunogenicity and immunotherapy responses.
Pau_Bernat_Esparza_Molto-767

Pau Bernat Esparza Moltó

Postdoctoral Fellow

I earned my Ph.D. in Jose M. Cuezva’s lab at Universidad Autonoma de Madrid, where I studied the tissue-specific expression of the ATPase Inhibitory Factor 1, which is the physiological regulator of the mitochondrial ATP synthase, and its role in neuronal function. In the Shadel lab, I continue my research on mitochondrial biology, currently focused on mitochondrial retrograde signaling and its role in innate immune signaling.
Alexandra-Moyzis-767

Alex Moyzis

POSTDOCTORAL FELLOW

Alex Moyzis received her PhD from UCSD in Dr. Asa Gustafsson’s lab, where she studied mitochondrial dynamics and mitophagy in cardiovascular disease. Moyzis was excited to join the Shadel lab, and is currently investigating how targeting various mitochondrial biogenesis and antioxidant pathways can combat T cell exhaustion and improve anti-cancer immune responses.

Mack-Reynolds-20240827-9E4A0499-77×767

Mack Reynolds

Postdoctoral Fellow

I received my PhD from the University of Michigan working in the laboratory of Dr. Mary O’Riordan, where I studied the regulation and function of mitochondrial metabolism in macrophage responses to bacterial infection. At Salk, I work jointly between the Shadel and Metallo labs, investigating immune and metabolic crosstalk during nucleic acid sensing and salvage.
Graduate Students

Matt Donnelly

Graduate Student

As a MD/PhD student, my interests in the Shadel lab lie at the intersection between basic science and human health. Small amounts of stress to mitochondria can induce long-term adaptive responses that overall benefit the organism. My goals in the lab are to characterize the mechanism behind these adaptive changes and test their potential as interventions for human disease.

Melissa Johnson

Graduate Student

Cancer cells are able to reconfigure their metabolism to support the energy demands of uncontrolled proliferation and promote survival in nonpermissive environments. I am interested in studying how and why this oncogene-directed metabolic reprogramming occurs, and what role it plays in immune evasion through metabolic crosstalk between cancer cells and T cells within the tumor microenvironment.

Gladys Rojas

Research Assistant III

I received my bachelor’s degree in biology at the University of San Diego. I’m currently involved in different projects in the Shadel lab including understanding the mechanism behind mtDNA release upon mitochondrial stress. In my spare time I like to knit, run and go hiking.

Deann Guan

LAB TECHNICIAN I

I am currently an undergraduate student at the University of California, San Diego studying Molecular and Cell Biology. In the Shadel Lab, I maintain the organization of supplies while also aiding fellow lab members in their projects to identify key metabolic pathways that contribute to oncogenesis and tumor immune responses. Outside of the lab, I enjoy playing tennis, painting, and occasionally splurging on things I don’t need.

Naomi Kelly

Lab Administrative Manager

After receiving my bachelor’s degree from the University of California at San Diego, my early career path was markedly varied. I have since spent the last 15+ years in Executive Administration and Research Support at independent research institutes in San Diego. I joined Salk and the Shadel lab in 2022.
Lab Manager
Kym_Miller-767

Kym Miller

Lab Manager

I obtained my PhD in Immunology from the University of California, Irvine and did my postdoc at Institut Pasteur, Paris. I joined the Shadel lab as lab coordinator in 2019 with the aim of investigating the role of mitochondria in innate immune responses. My favorites in life are Bisous (my dog), cheese, and the occasional liquid brunch with friends.
