John A. Rock (UC Riverside Ph.D. '07) has been an active member of nationally recognized programs designed promote the development and participation of underrepresented groups in the mathematical sciences. Immediately after earning his Ph.D., John worked with the organizers of the Pacific Coast Undergraduate Mathematics Conference (PCUMC) to bring large groups of undergrad math students to the event on an annual basis. This conference was cofounded by fellow alumnus Alissa Crans and recognized by the AMS as a Mathematics Program that Makes a Difference in 2015. John served as a co-organizer of PCUMC between 2012 and 2015.

John became involved with both the Math Alliance and the PUMP Program after attending the 2013 AfterMath Conference. In the summers of 2014 and 2015, John was the local co-organizer and an instructor for the PUMP Summer Program which took place at Cal Poly Pomona. Afterward, John served as the Co-Director of the PUMP Program from early 2015 to late 2016. The PUMP program led to the Department of Mathematics at CSU Northridge earning the Award for an Exemplary Program or Achievement in a Mathematics Department from the AMS in 2016 in recognition of the program's success in motivating students to pursue graduate degrees in mathematics. John has also been an Alliance Mentor since 2013, connecting math majors to the Math Alliance and their excellent resources in order to help these students find and apply to PhD programs. He now also serves on the Alliance Masters Programs Groups Committee which is searching for master's programs from across the country to become part of the Math Alliance. In particular, the hope is to have these programs serve as bridges between undergraduate and Ph.D. programs in mathematics.

Along with another fellow UC Riverside alumnus Erin Pearse (Ph.D. '06) and their colleague Tony Samuel, both now at Cal Poly San Luis Obispo, John was a Co-Principal Investigator and a primary organizer of the 2016 Summer School on Fractal Geometry and Complex Dimensions. (Tony is on the left and John is on the right of the included photo.) This conference celebrated the contributions of his thesis advisor Michel Lapidus on the occasion of the latter's 60th birthday by bringing together the world's preeminent fractal geometers (including Michael Barnsley, Kenneth Falconer, and Jun Kigami) to provide an introduction to the field for burgeoning students and young mathematicians from across the globe. Many of the participants were from groups underrepresented in mathematics with contingents from UC Riverside and Cal Poly Pomona.

John has been a professor of mathematics at Cal Poly Pomona since the fall of 2011. Currently he is an Associate Professor and the Graduate Coordinator for their MS program in mathematics. His research interests continue to lie primarily in fractal geometry (though with a small excursion into calculus pedagogy involving integration by parts), which he studied at UC Riverside under Michel Lapidus. Motivated by his experiences as a graduate student at UC Riverside, John actively involves his undergraduate and graduate students in research projects as often as possible, frequently resulting in publications co-authored with these student researchers.

Alissa S. Crans (UC Riverside Ph.D. ’04) has been recognized nationally for her enthusiastic ability to share mathematics, having been honored with the Hasse Prize for expository writing and Alder Award for distinguished teaching by the Mathematical Association of America. As a professor of mathematics at Loyola Marymount University, Alissa is known for her active mentoring and supporting of women and underrepresented students and is dedicated to helping all students increase their appreciation and enthusiasm for the discipline. She proselytizes about math in settings that range from the National Math Festival, the National Museum of Mathematics, and the MAA Distinguished Lecture Series to Nerd Nite Los Angeles and public school K-12 classrooms.

Alissa’s passion for broadening participation in mathematics was ignited during her first year at UCR through her experiences assisting Dr. Pamela Clute with the mathematics course for UCR’s FASTSTART program and as a teaching assistant for the Summer Mathematics Program for Women at Carleton College. During her final year at UCR, she and other advanced graduate students created a teaching assistant mentoring program, which to her pride, continues in the department today. These experiences fostered her commitment to helping form a more inclusive, diverse mathematical community.

This commitment continues throughout her career. She was honored when the American Mathematical Society recognized the Pacific Coast Undergraduate Mathematics Conference, which she cofounded with Kendra Killpatrick and Naiomi Cameron, with a “Programs that Make a Difference” award. Recently, Alissa became an Associate Director of MAA Project NExT, a professional development program of the Mathematical Association of America for junior faculty.

Alissa's research interests lie in the field of higher-dimensional algebra and involve categorifying algebraic structures called quandles with the goal of defining new knot and knotted surface invariants. She is also interested in the connections between mathematics and music, and enjoys playing the clarinet with the Santa Monica College wind ensemble. Her work has been supported by an NSA Young Investigator Grant and a Simons Foundation Collaboration Grant for Mathematicians. Recently, Alissa is the subject of an award-winning essay in Association for Women in Mathematics (AWM). https://sites.google.com/site/awmmath/programs/essay-contest/2016-results**Dr. Jose Gonzalez joins the UCR Math Department**

Dr. Jose Gonzalez has joined the department as a new Assistant Professor.

**John Baez to Speak at Winter Meeting of Canadian Mathematical Society**On December 5, 2015, Prof John Baez will give a public lecture at the winter meeting of the Canadian Mathematical Society in Montreal.

The title of his talk is "The answer to the ultimate question of life, the universe, and everything". It is about some curious mathematical properties of the number 42. According to Prof Baez, this is based on a joke by the writer Douglas Adams, in which the number 42 was the answer to the ultimate question. The CMS winter meeting is the primary annual mathematics meeting in Canada. The CMS annual meetings have been running since 1945, so this year marks their 70th anniversary. According to an organizer, the meeting typically has 300-400 participants, but this year will likely set a record -- closer to 500. The public lectures are meant to bring interesting mathematics to a broad audience. They are given by scientists of international renown who are also known for their efforts in mathematics outreach or popularization, or for bridging the gap between mathematics and other disciplines.

**John Baez to Speak at Broadcom**On November 18, 2015, UC Riverside Math Professor John Baez will give a talk on category theory and electrical circuits at Broadcom. Broadcom is a FORTUNE Global 500 company. It is a semiconductor company with more than 11,250 U.S. and 4,100 foreign patents. Prof John Baez has been invited by Broadcom's central engineering group.**Mathematician Named Fellow of American Mathematical Society**Mathematician Vyjayanthi Chari at the University of California, Riverside is one of only 50 mathematical scientists from around the world who have been named fellows of the American Mathematical Society (AMS) for 2016. Chari, a professor of mathematics, is honored for “contributions to the theory of quantum groups and affine Lie algebras, and for service to the mathematical community.”

“Dr. Chari has been well regarded by her colleagues for her contribution to mentoring graduate students and postdocs,” said Yat Sun Poon, the chair of the Department of Mathematics at UC Riverside. “She is well known among Lie theorists, and very well cited. She is leading UC Riverside’s Lie theory research group, and beyond. We are proud of her achievement, and feel fortunate that she is on our faculty.”**The 2014–15 Graduate Dissertation**Each year the Graduate Council and Graduate Division present the Doctoral Dissertation Advisor/Mentor Award to one or two UCR faculty members who have made outstanding contributions to the training of advanced graduate students. It is my pleasure to announce that this year’s winner is Vyjayanthi Chari. Dr. Vyjayanthi Chari is a Professor in the Department of Mathematics. She received her BS (1976) and PhD (1988) in Mathematics from Bombay University. She has been at UCR since 1991, where she started as an Associate Professor and is presently investigating new directions in Lie Theory. Over the years, Dr. Chari has mentored an impressive number of graduate students—27 in total; however, her students uniformly report that Dr. Chari provided timely guidance for professional, educational, and personal matters. Many students cited Dr. Chari as one of the most influential people in their lives. Furthermore, it is clear both from the eloquent nature of the supporting letters and the prestigious positions held by those who wrote them that Dr. Chari produces articulate, successful mentees. For her many efforts in mentoring graduate students, she is being honored with the Doctoral Dissertation Advisor/Mentor Award.

He was 74 years old.

Professor Gretsky joined the faculty in the Department of Mathematics in 1967 and retired in 2005. He was granted emeritus status in 2006. He also served as a visiting faculty member in the UCLA Department of Economics.

Born in Boston, Mass., he received a four-year Merit Scholarship to attend Caltech, where he earned his B.S. in mathematics in 1962. He earned his M.S. in 1964, followed by his Ph.D. in 1967, both in mathematics at Carnegie-Mellon University. He was a member of the American Mathematical Society, the Mathematical Association of America and the American Civil Liberties Union.

Professor Gretsky was a resident of Hermosa Beach for more than 45 years and was a local surfer and volleyball player who earned a second-degree black belt in karate. He wrote about jazz music for the Easy Reader newspaper for many years.

He is survived by his former wife Terry Gretsky, sons Aaron and Miles Gretsky, step-daughter Cindy Adams and her husband Marshall Adams, sister Nancy Gretsky-Bassel and her husband Howard Bassel, nephews Noah Bassel and Timothy Read, ex-wife Patricia Hogan, and step-grandchildren Taylor and Carolyn Adams. His extended family and friends shared with us that they loved him and will greatly miss him. He was an amazing person with a zest for life, the beach, mathematics, game theory, a keen intellect, knowledgeable on many topics, extraordinarily kind and an especially true friend.

His family and friends are planning to honor him with a paddle out in the ocean next summer.
