Current lab members

Happy Birthday!
Samantha Peeters, B.Sc. (Guelph) is a Ph.D. student identifying the DNA elements allowing human genes to escape X-chromosome inactivation.  She is doing this by integration of human DNA into the mouse X chromosome in collaboration with the Simpson lab at CMMT.  She is currently using CRISPR in a mouse embryonic stem cell line with two X chromosomes to generate a female cell line for targeting. Sam was featured in Faculty of Medicine’s ‘Back to School’ site
Karanveer(wlabcoat) Karanveer Bhangu, B.Sc. (York) joined the lab in September 2021.  He is currently using CRISPR to generate deletions of XIST in somatic cells. 
Brad Bradley Balaton, B.Sc. (Saskatoon) is a Ph.D. student studying genes that are variable in their escape from X-chromosome inactivation, so that they are subject to inactivation in some females, but escape from inactivation in other females.
Christine Christine Yang, (M.Sc. UBC) did her M.Sc. on using DNA methylation to examine silencing of transgenes.  She then undertook the lab’s first RNA and ChIP-seq studies (see Genome Biology paper) and has become the lab’s RIP-star.

Seymour is not a calico, that’s unique to cats!

Maria Jose Navarro Cobos joined the lab in 2019 from Mexico.
