Yesterday I found out via a comment on this blog that Yuval Peres, a person who has been accused by numerous students, trainees, and colleagues of sexual harassment, will be delivering a lecture today in the UC Davis Mathematical Physics and Probability Seminar.

The facts

I am aware of at least 11 allegations by women of sexual harassment by Yuval Peres (trigger warning: descriptions of sexual harassment and sexual assault):

1. Allegation of sexual harassment of a Ph.D. student in 2007. Source: description of the harassment by the victim.
2. Allegation of sexual harassment by a colleague that happened when she was younger. Source: description of the harassment by the victim.
3. Allegation of sexual harassment of a woman prior to 2007. Source: report on sexual harassment allegations against Yuval Peres by the University of Washington (received via a Freedom of Information Act Request).
4. Allegation of sexual harassment by one of Yuval Peres’ Ph.D. students several years ago. Source: report on sexual harassment allegations against Yuval Peres by the University of Washington (received via a Freedom of Information Act Request).
5. Allegation of sexual harassment of a colleague. Source: personal communication to me by the victim (who wishes to remain anonymous) via email after I wrote a post about Yuval Peres.
6. Allegation of sexual harassment of a graduate student. Source: personal communication to me by the victim (the former graduate student who wishes to remain anonymous) via email after I wrote a post about Yuval Peres.
7. Recent allegations of sexual harassment by 5 junior female scientists who reported unwanted advances by Yuval Peres to persons that leading figures in the CS community describe as “people we trust without a shred of doubt”. Source: a letter circulated by Irit Dinur, Ehud Friedgut and Oded Goldreich.

The details offered by these women of the sexual harassment they experienced are horrific and corroborate each other. His former Ph.D. student (#4 above) describes, in a harrowing letter included in the University of Washington Freedom of Information Act (FOIA) disclosed report, sexual harassment she experienced over the course of two years, and many of the details are similar to what is described by another victim here. The letter describes sexual harassment that had its origins when the student was an undergraduate (adding insult to injury the University of Washington did not redact her name with the FOIA disclosed report). I had extreme difficulty reading some of the descriptions, and believe the identity of the victim should be kept private despite the University of Washington FOIA report, but am including one excerpt here so that it’s clear what exactly these allegations entail (the letter is 4.5 pages long):  

Trigger warning: description of sexual harassment and sexual assault

“While walking down a street he took my hand, I took it away with pressure but he grabbed it by force. I was pretty afraid of getting in a fight with my PhD advisor. He stroked my hand with his fingers. I said stop, but he ignored it. I started talking about math intending to make the situation less intimate. But he used me being distracted and put his arms around my waist touching my bud. I was in shock. We came by a bench. He asked me to sit down. I removed his hands and sat down far from him. He came closer and told me that I had a body like a barbie doll. I changed topic again to math, but he took my hand and kissed the back of my hand. I freed my hand with a sudden move, and saw him leaning towards me touching my hair and trying to kiss me. I felt danger and wanted to go home. Yuval was again holding my hand, but this time there was no resistance from me. I thought if I let him hold my hand it is less likely that he harms me. Arriving at my home he tried to give me a kiss. I was relieved when he drove away.”

The victim sent this letter to the chairs of the mathematics and computer science departments at the University of Washington and made a request:

“I am not the only female who was sexually harassed by Yuval Peres and I am convinced that I was not the last one. Therefore, I hope with this report that you take actions to prevent incidents like this from happening again.”

Instead of passing on the complaint to Title IX, and contrary to claims by some of Yuval Peres’ colleagues that appear in the University of Washington FOIA disclosure report that the case was investigated, the chairs of the University of Washington math and computer science departments (in a jointly signed letter) offered Yuval Peres a path to avoiding investigation:

“As you know from our e-mail to you [last week], your resignation as well as an agreement not to seek or accept another position at the University will eliminate the need for the University to investigate the allegations against you.”

Indeed, Yuval Peres resigned within two months of the complaint with no investigation ever taking place. This is the email the victim received afterwards from the chair of the mathematics department, in response to her request that “I hope with this report that you take actions to prevent incidents like this from happening again”:

“I believe this resolution [Yuval Peres’ resignation] has promptly and effectively addressed your concerns.”

At least 8 women have since claimed that they were sexually harassed.

Seminar and a dinner

As is customary with invited speakers, the organizer of the seminar today wrote to colleagues and student in the math department at UC Davis on Monday letting people know that “there will be a dinner afterward, so please let me know if you are interested in attending.”

Here is a description of a dinner Yuval Peres took his Ph.D. student to, and a summary of the events that led to him and his Ph.D. student walking down the street when he forcibly grabbed her hand:

Trigger warning: description of sexual harassment and sexual assault

“I tried to keep the dinner short, but suddenly he seemed to have a lot of time. He paid in cash in contrast to dinners with other students, and offered to take me home. In his car half way to my place he said he would only take me home if I show him my room (I was living in a shared apartment with other people). I thought it was a joke and said no. He laughed and grabbed my hand. Arriving at home I said goodbye. But when I got out of the car he said that I promised to show him my room. I said that I did not. However, he followed me to the backdoor of the house. Fortunately some of my roommates were at home. It bothered Yuval that we were not alone at my home, so he said we should take a walk outside. I felt uncomfortable but I still needed to talk about my PhD thesis work. While walking down the street he took my hand, I took it away with pressure but he grabbed it with force…”

I wonder how many graduate students at UC Davis will feel comfortable signing up for dinner with Yuval Peres tonight, or even be able to handle attending his seminar after reading of all the sexual harassment allegations against him?

The challenge is particularly acute for women. I know this from comments in the reports of sexual harassment that I’ve read, from the University of Washington FOIA disclosed report, and from personal communication with multiple women who have worked with him or had to deal with him. Isn’t holding seminars (which are an educational program) that women are afraid to attend, and are therefore de facto excluded from and being denied benefit of, in a department that depends heavily on federal funding, a Title IX violation? Title IX federal law states that

“No person in the United States shall, on the basis of sex, be excluded from participation in, be denied the benefits of, or be subjected to discrimination under any education program or activity receiving Federal financial assistance.”

An opinion

It’s outrageous that UC Davis’ math department is hosting Yuval Peres for a seminar and dinner today.

[Update November 10th, 2019: after reading this post a former Ph.D. student at UC Berkeley wrote that “Another PhD student in Berkeley probability and I both experienced this as well. About time this is called out so no more new students are harassed.“]
