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

Tom & X

Thomas Dixon-McDougall, B.Sc. (Toronto) is a Ph.D. student studying the domains of the XIST RNA that are critical for the RNA to localize in cis, recruit chromatin modification, and silence flanking genes.  He is currently using CRISPR to generate deletions along the X chromosome and uses FISH (he generated the ‘X’ on the header); immunohistochemistry; and allelic analyses to examine the impact of the deletions.
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.
