Education: B.S., Stanford University; 
Ph.D., Princeton University

Sue started at Fred Hutch in 2000 after completing post-doctoral work in Dr. Andrew Murray's lab at UCSF. She was trained as a geneticist but will use any technique necessary to answer a scientific problem. Although her major interests are the cytoskeleton, cell cycle and chromosome biology, she keeps an eye out for an interesting scientific problem. She enjoys mentoring and wants everyone in the lab to achieve their personal goals. When she is not in the lab, she enjoys hanging out with her family (i.e. carpooling) or running with their hyperactive mini-Aussie.  

Daniel Barrero

Daniel Barrero

Title: Graduate Student
Phone: 206.667.5766

Education: B.S., University of Redlands

Daniel joined the Biggins lab in 2019, and is co-advised with the Asbury lab at UW. As an undergraduate he studied signaling pathways that drive preterm birth using murine models, but discovered a love of structural biology and biophysics while working as a technician in the Puglisi lab at Stanford studying HIV reverse transcription. For his graduate work, Daniel is interested in using biochemical, structural, and biophysical tools to investigate how the architecture of the kinetochore allows both for its unique function, and for that function to be tuned through out the cell cycle. When he’s not busy pipetting tiny volumes of clear liquids into other clear liquids, Daniel enjoys practicing Brazilian jiu-jitsu, listening to podcasts, and slowly accruing house plants until his apartment becomes a jungle.

Title: Lab Aide
Phone: 206.667.5766

Education: Current: University of Washington


Hi I’m Marlisa! I’m known for never wearing the same outfit twice! I’m really into fashion. I was born and raised in South Seattle. I’m proud to say I’m a 1st- generation college student! I am a current undergraduate student at the University of Washington. GO DAWGS! I lovvvvveeee science and research thus far but, I also have a big interest in Public Health and Medicine! By the way I’m not new here at all. In 2016 I did the summer high school internship program in the Paddison Lab and recently over summer 2018 an internship in the Stoddard Lab. So, if you want to know more about Homing Endonucleases I’m your girl! Fun fact about me is I love to dance. I’ve been dancing since the age of 4! I am a part of the Hip-Hop team at the UW and have been performing at various places all over the city.

Sabrine joined the Biggins lab as a post-doc in early 2017 and is interested in understanding the role of centromere transcription and non-coding RNAs in the regulation of kinetochore assembly and function. Originally from France, she received her PhD from Paris Diderot University in the lab of Claire Francastel, where she studied the interplay between the DNA damage response and centromeric chromatin in murine cells. Outside of lab Sabrine enjoys baking, traveling and playing soccer on rainy Sunday mornings.

Jake Herman

Jake Herman

Title: Postdoctoral Research Fellow
Phone: 206.667.5766

Education: B.S., Western Washington University;
Ph.D., Colorado State University

Growing up in small-town WA, Jake started his scientific career as a way to avoid playing on sports teams - in the intervening years it grew to be a passion. He began studying kinetochore biology during his graduate work at Colorado State University where Jake worked in Dr. Jennifer DeLuca’s Lab. In 2015 he returned to the NW and started a postdoc at Fred Hutch, where Jake aims to understand the fundamental mechanisms by which cells detect and correct errors in kinetochore-MT attachments and to exploit that understanding for therapeutic development. He collaborates with the Paddison Lab to leverage CRISPR technology to identify kinetochore activities specifically required for survival of cancers. His work utilizes yeast, mouse, and human experimental systems.
