Chantal joined the Khvorova Lab in 2017 with an interest in developing new tools to understand and treat neurological disorders. Her thesis work aims to understand the spatial and functional relationship between brain and liver Apolipoprotein E and their impact on the Alzheimer disease pathogenesis. Using chemically modified siRNAs, Chantal aims to identify hyper functional siRNAs that modulate the expression of genes associated with the onset of Alzheimer disease (ApoE, Tau, SNCA) in rodent and large animal models. The ability to modulate the expression of disease related genes in the rodent and non-human primate brain allows us to investigate their role in brain function, aging, and disease in the context of a living brain, and provides opportunities for the development of novel therapeutics.

He has two primary focuses in the lab: (1) investigating the effect of different chemical modification patterns on intracellular siRNA trafficking, and (2) studying the potential pathogenic role of repeat-expanded RNA cluster formation in Huntington’s disease. Outside of the lab, Soki enjoys movies, music, video games, board games, sports, and is particularly addicted to tennis.

Bruno Godinho received his foundational pharmacy training while pursuing his bachelor's degree at the Lisbon School of Health Technology (Portugal). During his time in college, he undertook research internships at Utrecht University (The Netherlands) and Universidade NOVA de Lisboa (Portugal), which were key in shaping his interest in a career in scientific research. His master's degree in clinical pharmacology, obtained from the University of Glasgow (Scotland, UK), was an important stepping stone that allowed him to foster his interest in gene therapy and gene silencing for the first time. He later received his doctorate degree from University College Cork (Ireland), where he studied formulation-based approaches for delivery of therapeutic oligonucleotides to the central nervous system (CNS). In early 2015, he joined Prof Khvorova’s lab as a postdoctoral fellow to gain experience in the design and delivery of fully-modified conjugated therapeutic oligonucleotides. Together with colleagues within the lab and through vibrant collaborations with neighboring labs at the RNA Therapeutics Institute, he has furthered the understanding of the pharmacokinetics and pharmacodynamics of therapeutic oligonucleotides in the CNS. His work has great impact for diseases such as Huntington’s Disease (HD) and Amyotrophic Lateral Sclerosis (ALS). While a postdoc, Bruno also acted as an invited adjunct professor at the Lisbon School of Health Technology, where he taught pharmacy-related subjects, including basic pharmacology, toxicology, and pharmacokinetics. He is also a guest lecturer in a master's degree program in biomedical engineering (Instituto de Engenharia de Lisboa ISEL/ESTeSL, IPL).

When not involved in scientific discussions or experiments, Bruno can be found out in the world. He has a great passion for the outdoors, from hiking to biking to backpack travelling with his family. Waste no time, waste no life.

Vignesh (Viggy) is a molecular biologist who obtained his bachelor’s degree at the Amrita School of Biotechnology, India and an integrated MS-PhD degree from the Indian Institute of Science, where he studied and discovered novel pathways that the human pathogen Mycobacterium tuberculosis uses to sense and respond to its surroundings. He is passionate about developing new therapeutics for human diseases and is currently working on the characterization of oligonucleotide therapies for preeclampsia and MECP2 duplication syndrome.

After failing to gain admission to the Hogwarts School of Witchcraft and Wizardry, Zack decided to pursue a career in biology. Zack graduated Northeastern University with a bachelor’s degree in biology, during which he focused on applied ecology, performing field work in Massachusetts, the Atlantic Ocean and Peru.
