Hilary Coller's Research at UCLA: Cell Quiescence, Wound Healing, and Student Perspectives
Hilary Coller is a distinguished researcher at UCLA whose work focuses on cell quiescence and its implications for various biological processes, including wound healing and cancer. Additionally, she is an engaging and supportive professor, highly regarded by her students. This article explores Coller's research contributions and provides insights into her teaching style and courses at UCLA.
Unveiling the Secrets of Cell Quiescence
Coller's research delves into the intricate mechanisms governing cell quiescence, a state in which cells are temporarily inactive but capable of re-entering the cell cycle. Quiescence is a common state for many somatic cells including stem cells, and the failure to appropriately regulate the transition between quiescence and proliferation underlies several common and lethal disorders including cancer. Contrary to the traditional view of quiescence as a passive state, Coller’s research suggests that quiescence, commonly thought of as an inactive or sleepy state, is an active and highly regulated process. Her work has demonstrated that cells undergo significant changes in gene expression, metabolite profiles, and microRNA activity as they transition between proliferation and quiescence.
To unravel the complexities of quiescence, Coller leverages sophisticated technologies and computational approaches to understand the cellular networks that underlie quiescence. She applies next-generation sequencing, as well as mass spectrometry proteomics and metabolomics, to generate high-quality datasets defining the characteristics of proliferating and quiescent cells. Coller has also developed specific computational and algorithmic approaches for analyzing and interpreting these datasets.
Implications for Wound Healing and Tissue Regeneration
Coller's research into the transition between quiescence and proliferation could have major implications for healing chronic wounds and developing methods to regenerate damaged or diseased tissues and organs. A key focus is identifying the molecular signals that trigger quiescent cells to spring to action, informing the development of therapies to regenerate damaged or diseased tissue. Coller aims to discover the molecular signals, such as proteins, that trigger quiescent cells to spring to action, informing the development of therapies to regenerate damaged or diseased tissue.
In one notable project, Coller was among a team of UCLA researchers who discovered a new protein factor that contributes to a fibroblast cell’s ability to migrate to a wound and participate in its healing process. This discovery could open new avenues for treatments that prevent cancer cells from using the same mechanisms to spread throughout the body.

Student Experiences in Hilary Coller's Classes
Hilary Coller is not only a leading researcher but also a dedicated and well-respected professor at UCLA. Student reviews consistently praise her teaching style, her commitment to student learning, and the real-world relevance of her courses.
Many students describe Coller as an amazing professor who cares about her students. She is often commended for being extremely intelligent and organized and nice. Her passion for cell biology is evident in her engaging lectures and her ability to clearly explain complex concepts. Students appreciate that she is very clear on what will be tested and you learn so much involving cell biology.
Coller's courses often incorporate a flipped classroom model, where students watch background videos before lecture and then expand on the concepts in class. You will also be expected to read 5 research papers throughout the quarter and the figures will be expanded on in the class. They are tested in all of the exams so make sure you know the figures really well.
The emphasis on research papers and experimental design is a recurring theme in student reviews. Questions involved a lot of experimental design using the methods taught in class. Students find this approach valuable because it exposes them to real techniques that are used in a research lab. This class is so cool because it has so many applications to real-life and the lab setting. You learn about real techniques that are used in a research lab.
Course Structure and Assessment
Coller's courses typically involve a combination of quizzes, midterms, and a final exam. Your grade is dependent on 3 quizzes (25%), 2 midterms (20+25%), and 1 final exam (30%), with the lowest quiz score being dropped. You can also get up to 5 points extra credit on all the midterms and final. Many students mention the availability of extra credit opportunities, which can significantly boost their grades. She provides past exams and quizzes so you can get a feel for how she likes to ask questions.

The format of exams may vary, with some being take-home and open-note, while others require a lockdown browser and webcam recording. LOCKDOWN BROWSER + WEBCAM RECORDING REQUIRED FOR EXAMS NOW. No notes.
While discussion sections are often optional, they can be helpful for reviewing exam answers. Discussions are not mandatory, but they go over exam answers in them. BruinLearn site has all slides, past exams to use for reference. Textbook is really not necessary. Lectures are engaging and informative, and are posted on Bruincast, attendance is not mandatory. There really isn't any homework except watching a 30ish min background video weekly and reading 6 research papers throughout the quarter.
Challenges and Rewards
Some students note that Coller's courses can be demanding, particularly with the weekly quizzes and the need to thoroughly understand research papers. There were many weeks where we had a quiz one week and then a midterm immediately the next week and then another quiz the following week. However, the consensus is that the workload is manageable if students stay engaged with the material and take advantage of the resources provided. If you go to lecture, watch any pre-lecture videos, and read the assigned papers, you will do just fine. I went to some of the office hours to ask questions about concepts and figures from the papers… it helps A LOT.
Despite the challenges, students consistently express that Coller's courses are among their favorites at UCLA. This has been one of my favorite classes at UCLA thus far. I found the class content to be extremely interesting. They appreciate her passion for the subject matter, her dedication to student learning, and the real-world applications of the material. After having a challenging winter quarter, Dr. Coller and the TA's rekindled my love for research. Her lectures are engaging and the material covered is super manageable.
