Mammalian Target of Rapamycin Complex 1 (mTORC1) coordinates cell growth with the availability of nutrients, including extracellular amino acids. The signaling pathway that regulates mTORC1 in response to amino acids remains a poorly understood. I am investigating the cellular signaling pathways that control mTORC1 activity in response to the cell surface amino acid receptor dimer T1R1/T1R3. I particularly focus on heterotrimeric G proteins and their role in transmitting signals from the receptors to mTORC1.

I aim to study the mechanisms that govern the speed and amplitude with which Gαq and PLC-β3 respond to receptor stimulation by one or more agonists. Towards this end, I am currently working to establish a FRET assay to monitor Gq/PLC-β3 binding.

I am interested in understanding the mechanisms of PLC-β regulation by Gβγ. Currently, I am using mutational analysis combined with biochemical assays and binding studies to probe Gβγ interactions with PLC-β and Gαq. Outside lab, I love to travel, am a keen long distance runner and pursue photography as a hobby.
