September 2023 QCB Newsletter

e-Newsletter Volume 3 Issue 6 | September 2023

Department of Quantitative and Computational Biology

In this month’s newsletter we are looking back at graduation and include the placement of our most recently graduated undergraduate class. When we started the QBIO major, we needed to decide between an easy major that would have grown much faster or a smaller major that provides meaningful skills for the students. We decided for the latter, to provide training for the 21st century.

The QBIO major is now a major with more than 100 students. Despite the challenging courses that we require, all students complete the program on time, and the success of the students is impressive. The Medical School acceptance rate is 100% and the MD/PhD Program acceptance rate is 100% too. QBIO students get accepted to the best graduate schools in the country, or find excellent jobs in industry.

In faculty news, Dr. Matt Pennell and colleagues were successful in establishing the new Center for Ecological and Evolutionary Dynamics (CEED), and Dr. Seva Katritch and colleagues were successful in expanding the Center for New Technologies for Drug Discovery and Development (CNT3D). These centers link QCB directly with other departments and schools through new seminar series and collaborations.

I want to end with an invitation for everyone to attend Dr. Mark Chaisson’s Tenure Talk entitled ‘Computational tools for individual and population-scale discovery of complex genetic variation from single-molecule sequencing’ this Thursday, October 5th, at 2 pm, in RRI 101, or on Zoom.

Remo Rohs, Ph.D.

QCB Department Chair

QCB Faculty

Dr. Naomi Levine published a study in Science Advances introducing a new proteome allocation model to investigate the relationships between temperature, size and metabolism among marine phytoplankton. They applied the model to decipher the mechanisms behind both short-term (acclimation) and long-term (adaptation) responses, providing insights into the metabolic trade-offs that a cell faces while managing stress, space and energetic constraints. These results have implications for rates of carbon sequestration and export in a warmer ocean.

Dr. Matt Pennell (left), Dr. Melissa Guzman, and Dr. Jazlyn Mooney, with colleagues from Biological Sciences, Keck, and Viterbi, founded a new Center for Ecological and Evolutionary Dynamics (CEED). Phase 1 funding from the Dornsife College will support a seminar series, establish a CEED community at USC and beyond, and enable the hosting of the Southern California Evolutionary Genomics meeting at USC.

Dr. Seva Katritch (QCB) and Dr. Charles McKenna (CHEM) received Phase 2 funding from the Dornsife College to expand the Center for New Technologies for Drug Discovery and Development. In addition to the CNT3D seminar series and short courses, the funding will support student co-advising between CNT3D member labs, as well as pilot computer-driven drug discovery projects in collaboration with groups across both USC campuses.

Dr. Remo Rohs is co-PI of a new center together with colleagues from the Viterbi School of Engineering and the Price School of Public Policy. This center is led by Dr. Urbashi Mitra, with the goal of developing methods and technology to study emerging infectious diseases and pandemic spillover events.

Dr. Serghei Mangul received a new NSF grant for undergraduate education. This collaborative project aims to equip undergraduate students with essential skills in big data analytics, bridging an educational gap at community colleges and minority-serving institutions (read here). Dr. Mangul also published a new paper “Scientists without borders: lessons from Ukraine” on how to help the scientific community in Ukraine by reaching out, providing accessible training opportunities, and developing collaborations that increase inclusion and connectivity (read here).

QCB Graduate Students

This month, the Computational Biology Student Association (CBSA) organized multiple events for graduate students and postdocs to engage the student body. One of the highlights was a cozy crafting night, where students created collages based on their happy place. In addition, the student government organized an educational trip to the Natural History Museum with a special tour about entomology by Austin Baker Ph.D. His enthusiasm for entomology was infectious, as he shared his experiences from years of fieldwork, offering fascinating anecdotes and knowledge about insect behavior and conservation efforts. The highlight of the tour was the chance to examine a wide array of insect specimens up close, from rare butterflies to bizarre beetles.

Anna Nadtochiy, a CBB PhD student in Dr. Scott Fraser's lab, published a first-author Bioinformatics paper (link here) for the time annotation and management of volumetric functional imaging data. Anna also defended her PhD thesis on September 29th and becomes Dr. Fraser's first graduate from the CBB Program.

QBIO Undergraduate Students

QBIO student leaders, along with Dr. Remo Rohs, represented the QCB Department at a student career event at La Cañada High School. This group presented the QBIO major to students and parents, shared their experiences within the department, and ultimately encouraged them to apply to USC and QBIO. The representatives pictured are: Karen Lee, Wade Boohar, Brandon Ye, and Colin Yeo.

The undergraduate Quantitative Biology Association (QBA) had a successful first meeting as a student organization in September. The event introduced the QBA executive board and focused on student networking, giving organization members a chance to connect with their peers as they approach the new academic semester together.

Jordan Cahoon, a QCB Department junior who completed a minor in Computational Biology and Bioinformatics, was named a Goldwater Scholar. Jordan is interested in genetics and computational biology, and hopes to pursue a PhD in one of these topics after she graduates. Read more about her accomplishment here.
