I use a multidisciplinary approach, leveraging microscopy, genetics, and

biochemistry techniques to answer fundamental questions in plant cell biology.

Specifically, my work focuses on understanding the role of the SCD complex in

membrane trafficking and cytokinesis. Through my work, we have discovered

that SCD1 and SCD2 form a protein complex that functions in exocytosis through

downstream interactions with RabE1 and the exocyst. This work sheds new light

on exocytic vesicle trafficking and provides a mechanism for regulated exocytosis in plants.

My work focuses on understanding the proteins that mediates clathrin coated

vesicular trafficking in Arabidopsis through proteomic characterization of the

vesicles. Outside of lab I enjoy spending my days outdoors in nature camping,

backpacking, fishing, etc. Whenever possible I spend nights observing the stars,

cultivating an amateur astronomy hobby.

My work focuses on understanding the role of a pythohormone in proper cell

division and expansion in plants. Outside of lab I like to play volleyball, hike,

and do other outdoors activities.

My work focuses on studying an evolutionarily conserved chaperone-like 

AAA ATPase, AtCDC48, and its interaction with a potential regulator, PUX1.

My aim is to elucidate the mechanism of AtCDC48 disassembly induced by

PUX1 as well as to determine the extent to which PUX1-mediated disassembly

is involved in AtCDC48 turnover. When I’m not in lab, I’m baking (for the lab),

cooking (mostly for me), and reading.

I currently work on two projects: 1) mapping a second site suppressor mutation in Arabidopsis and 2) assessing the interaction of two nucleating proteins during cytokinesis in Arabidopsis. In my free time I like to go for walks along the lakeshore path, read, and hang out with friends.
