He served as the 6th chancellor of the University of California, Los Angeles from 2007 to 2024. Previously at the University of Virginia, he served as executive vice president and provost from 2001 to 2007, vice president for research and public service from 1998 to 2001, and vice provost for research from 1993 to 1998.

Early life and education

Block was born in Monticello, New York, the grandson of Jewish immigrants from Eastern Europe.{{cite web |first=Larry |last=Gordon |title=Yes, Virginia, he's coming to lead UCLA |website=Los Angeles Times |date=June 24, 2007 |url=https://www.latimes.com/archives/la-xpm-2007-jun-24-me-block24-story.html |access-date=March 4, 2015 |archive-date=April 2, 2015 |archive-url=https://web.archive.org/web/20150402161904/http://articles.latimes.com/2007/jun/24/local/me-block24 |url-status=live}} His father and uncle owned Mountain Dairies, a retail/wholesale distributor that served many of the hotels and camps that populated Catskill region of New York. During summers, he worked at the dairy as a truck driver. He played varsity tennis at Monticello High School.

Block attended Foothill College{{Cite web |title=Foothill College on LinkedIn: UCLA Chancellor Gene Block (pictured here with some Foothill College… |url=https://www.linkedin.com/posts/foothill-college_ucla-chancellor-gene-block-pictured-here-activity-7062931904131469312-G3HA/ |access-date=January 30, 2025 |website=www.linkedin.com |language=en}} and then received a Bachelor of Arts with a major in psychology from Stanford University in 1970. He received a Master of Science in 1972 and a Doctor of Philosophy in 1975 in psychology from the University of Oregon.{{cite thesis |title=Efferent control of the circadian oscillator in the eye of Aplysia. |date=1975 |institution=University of Oregon |degree=Ph.D. |last=Block |first=Gene David |id={{ProQuest|302729825}} |oclc=}}{{Cite web |title=Gene Block, Ph.D. – UCLA Brain Research Institute (BRI) |url=https://bri.ucla.edu/people/gene-block/ |access-date=January 6, 2024 |language=en-US}}

From 1975 to 1978, he returned to Stanford for postdoctoral work with Donald Kennedy (who later became the 8th president of Stanford) and Colin Pittendrigh (who is known as the “father of biological timing"). During his postdoctoral research years, Block studied how voluntary movements inhibit sensory feedback in the crayfish working in the Kennedy lab while studying issues of circadian biology with Colin Pittendrigh.

== University of Virginia ==

In 1978, Block became a member of the faculty in the Department of Biology of University of Virginia. Here, Block served as the vice provost for research from 1993 to 1998, vice president for research and public service from 1998 to 2001, and then in 2001 he was appointed as executive vice president and provost. Furthermore, during this time from 1991 to 2002, Block also served as the founding director of the National Science Foundation Science and Technology Center in Biological Timing.{{cite web |url=http://www.universityofcalifornia.edu/news/article/20361 |title=Curriculum Vitae Gene D. Block |publisher=University of California |archive-url=https://web.archive.org/web/20130419214459/http://www.universityofcalifornia.edu/news/article/20361 |archive-date=April 19, 2013 |url-status=dead}}

According to Block, “The center raised the national visibility of the University in biological and medical research, and gave us reputational leverage in the U.S. as well as in Europe and Japan... Most importantly, the center's scientific accomplishments have been spectacular. We’ve done some high-risk research that has paid off greatly; some of it has fundamentally changed our understanding of biological processes.”{{cite web |url=http://www.virginia.edu/insideuva/2002/11/bio_timing.html |title=Clock stops on NSF biological timing center, but the momentum carries on |archive-url=https://web.archive.org/web/20080907110301/http://www.virginia.edu/insideuva/2002/11/bio_timing.html |archive-date=September 7, 2008 |url-status=dead |first=Fariss |last=Samarrai |date=March 29, 2002 |work=Inside UVA |publisher=University of Virginia}}

One of the center's biggest advances, largely by Joseph Takahashi, was the development of a mutant mouse that allowed for the identification and cloning of the “Clock” gene for the biological clock in a mouse in 1997. This was the first such gene to be identified at the molecular level in a mammal. This groundbreaking discovery was a result of the Clock Genome Project, which uses "forward genetics" to discover the genes regulating circadian clocks in mice, fruit flies, and plants. In addition, this work also led to the discovery of many other genes that regulate the biological clock.{{cite web |url=https://www.nsf.gov/news/news_summ.jsp?cntn_id=102795 |title=First Circadian Clock Gene Identified and Cloned in Mammals |publisher=National Science Foundation |access-date=April 6, 2018 |archive-date=June 20, 2018 |archive-url=https://web.archive.org/web/20180620002109/https://www.nsf.gov/news/news_summ.jsp?cntn_id=102795 |url-status=live |date=May 15, 1997}}

In 1997 and 1998, the reputable journal Science ranked the findings of the NSF Center in Biological Timings among the top 10 in biological research breakthroughs.

Three of the NSF Center investigators, Jeffrey C. Hall, Michael Rosbash and Michael W. Young,{{clarify|date=February 2023|reason=None of the existing citations mentions these person's relationship with either Science and Technology Center in Biological Timing or Gene Block.

Block was appointed Chancellor of UCLA in 2007. His selection was announced on December 21, 2006, succeeding interim office holder Norman Abrams on August 1, 2007.{{Cite web |url=http://newsroom.ucla.edu/releases/Gene-D-Block-Named-New-UCLA-C-7611 |title=Gene Block named new UCLA chancellor |last=Stogsdill |first=Carol |website=UCLA Newsroom |language=en |access-date=June 19, 2018 |archive-date=September 30, 2022 |archive-url=https://web.archive.org/web/20220930195503/https://newsroom.ucla.edu/ |url-status=live}}

On February 24, 2014, Block published an open letter to the campus community, expressing his opposition to Proposition 209, stating that the proposed merit-based selection system would damage diversity on campus.{{Cite web |url=http://chancellor.ucla.edu/updates/the-impact-of-proposition-209-and-our-duty-to-our-students |title=The Impact of Proposition 209 and Our Duty to Our Students |access-date=February 28, 2014 |archive-date=March 5, 2014 |archive-url=https://web.archive.org/web/20140305202918/http://chancellor.ucla.edu/updates/the-impact-of-proposition-209-and-our-duty-to-our-students |url-status=live}}

He has been widely criticized for the 2022 suspension of highly awarded professor of ecology Priyanga Amarasekare without documentation, viewed as retaliation for her calls for reform of a culture of discrimination at UCLA.{{cite journal |title=Exclusive: Documents raise questions about UCLA's suspension of ecologist |journal=Nature |year=2023 |doi=10.1038/d41586-023-00473-8 |url=https://www.nature.com/articles/d41586-023-00473-8 |access-date=February 25, 2023 |last1=Tollefson |first1=Jeff |pmid=36829063 |s2cid=257183409 |url-access=subscription}}

== Cell-autonomous circadian pacemakers ==

While at the University of Virginia, Block worked extensively with his graduate student, Douglas G. McMahon, the 1986 winner of the Society for Neuroscience's Donald B. Lindsley Prize in Behavioral Neuroscience, on the functioning of the circadian pacemaker system at the cellular level in Bulla gouldiana. In 1984, Block's students conducted a continuous 74-hour intracellular recording in constant darkness that demonstrated that basal retinal neurons (BRN) in the Bulla eye exhibit clear circadian rhythms. These rhythms were also shown to be correlated one-for-one with compound action potentials produced by the optic nerve.{{cite journal |last=McMahon |first=Douglas G. |title=Cellular analysis of the Bulla ocular circadian pacemaker system |journal=J Comp Physiol A |year=1984 |volume=155 |issue=3 |pages=379–385 |doi=10.1007/bf00610591 |s2cid=35743849}} The change in membrane potential of the BRNs, which are electrically coupled, were shown to precede or occur simultaneously with the increased compound action potential frequency. An increase in firing frequency, and depolarization of the BRNs, was seen during the day, and the reverse at night. These results demonstrated that the BRNs were at minimum an output for the pacemaker pathway and provided evidence that they were good candidates for being circadian pacemaker neurons.

This research was expanded several years later by a breakthrough study published in Science in which Stephan Michel and others working in Block's laboratory demonstrated that circadian rhythms in BRN membrane conductance could persist spontaneously in isolated BRNs.{{cite journal |last=Michel |first=Stephan |title=Circadian Rhythm in Membrane Conductance Expressed in Isolated Neurons |journal=Science |year=1993 |volume=259 |issue=5092 |pages=239–241 |pmid=8421785 |doi=10.1126/science.8421785 |bibcode=1993Sci...259..239M |display-authors=etal |url=https://zenodo.org/record/1231259 |access-date=July 4, 2019 |archive-date=July 28, 2020 |archive-url=https://web.archive.org/web/20200728173014/https://zenodo.org/record/1231259 |url-status=live}} These spontaneous circadian rhythms were shown for BRNs in isolation from other retinal cells and in isolation from each other. They showed that these circadian rhythms in membrane conductance were caused primarily by a potassium ion current. BRNs in isolation demonstrated the same patterns shown in Block's previous work in which membrane conductance decreased at dawn and increased at dusk. That similar patterns were seen in isolated cells as in previous multiple cell cultures provided the first strong evidence that individual neurons possessed the capacity to generate circadian rhythms. This research definitively concluded that BRNs are both necessary and sufficient for photoentrainment in Bulla.

== Necessity of calcium flux for rhythmicity ==

Block and colleagues hypothesized that ion movement across cell membranes plays a role in the generation of circadian rhythms. In 2005, his lab measured rhythms in rat suprachiasmatic nuclei (SCN) in various concentrations of calcium ions. Block found that as calcium concentration decreased, thus lowering the transmembrane ion movement, the amplitude of circadian rhythmicity also decreased.{{cite journal |last=Lundkvist |first=Gabriella |author2=Yongho Kwak |author3=Erin Davis |author4=Hajime Tei |author5=Gene Block |title=A calcium flux is required for circadian rhythm generation in mammalian pacemaker neurons |journal=The Journal of Neuroscience |date=August 17, 2005 |volume=25 |issue=33 |pages=7682–7686 |pmid=16107654 |doi=10.1523/JNEUROSCI.2211-05.2005 |pmc=6725395 |doi-access=free}} With no calcium added, there was no circadian rhythm at all. Block's lab repeated the experiment with rat liver tissue and mouse SCN tissue and found the same results in each case. This demonstrated that across species and tissues, transmembrane calcium flux is necessary for the generation of circadian rhythms. However, there are still some questions about the function of calcium flux. In this experiment, Block also tried adding calcium channel Blockers to the tissues. Rhythmicity did disappear, but it took several cycles, and it is unknown why rhythmicity was not immediately abolished. In addition, Block suspects that calcium flux plays a role in the entrainment of the mammalian clock to the environment, similar to its role in mollusk entrainment.

== Effects of aging on the circadian clock ==

Block has also studied the effect that aging has on the circadian system, collaborating with other leading chronobiologists including Michael Menaker. In 2002, he studied rhythmicity in rats of various ages and found that aging affected rhythmicity differently in different tissues. In the SCN, the intrinsic period shortened with age, while lung tissue often became arrhythmic (showing sporadic activity) and pineal and kidney tissues became phase advanced.{{cite journal |last=Yamazaki |first=Shin |author2=Marty Straume |author3=Hajime Tei |author4=Yoshiyuki Sakaki |author5=Michael Menaker |author6=Gene Block |title=Effects of aging on central and peripheral mammalian clocks |journal=Proceedings of the National Academy of Sciences |date=August 6, 2002 |volume=99 |issue=16 |pages=10801–10806 |pmid=12149444 |doi=10.1073/pnas.152318499 |pmc=125050 |bibcode=2002PNAS...9910801Y |doi-access=free}} In 2008, Block exposed rats of various ages to different light cycles, and found that phase advances took longer in the SCN in old rats than in young rats, but pineal tissues advanced faster in older rats. Liver tissues did not phase shift at all when the light cycle was advanced.{{cite journal |last=Davidson |first=Alec |author2=Shin Yamazaki |author3=Deanna Arble |author4=Michael Menaker |author5=Gene Block |title=Resetting of central and peripheral circadian oscillators in aged rats |journal=Neurobiology of Aging |date=March 2008 |volume=29 |issue=3 |pages=471–477 |pmid=17129640 |doi=10.1016/j.neurobiolaging.2006.10.018 |pmc=1635489}} These studies together have shown how complex the aging process is in the circadian system. Block notes that some, though not all, of these changes are likely influenced by diminishing synchronizing signals from the SCN. In 2006, Block observed that jetlag significantly increased the death rate in older mice, which highlights the medical importance of understanding the aging process of the circadian system.{{cite journal |last=Davidson |first=AJ |author2=MT Sellix |author3=J Daniel |author4=S Yamazaki |author5=M Menaker |author6=GD Block |title=Chronic jet-lag increases mortality in aged mice |journal=Curr Biol |date=November 7, 2006 |volume=16 |issue=21 |pages=R914-6 |pmid=17084685 |doi=10.1016/j.cub.2006.09.058 |pmc=1635966 |bibcode=2006CBio...16.R914D}}
