Since 2019, I have taught a class on Mathematics and Politics several times (including in Wellesley’s First Year Seminar program and as a short workshop . Check out the teaching modules the students made in two of those classes.

I co-founded the Institute for Mathematics and Democracy in 2019.

I have been supervising independent studies on mathematics and politics, one focusing on new applications of some classical power indices and another on some combinatorial topology aspects of voting theory.

Since 2019, I have been giving talks on mathematics and democracy, including at the Albright Institute for Global Affairs, Wellesley High School, etc. Some of the slides from the talks I gave on this topic can be found on the talks page.

I taught a class on cryptography and privacy in Wellesley’s First Year Seminar program in spring 2015.

## Bosnia-Herzegovina

For the last ten years, I have been a member of and actively involved with the Bosnian-Herzegovinian American Academy of Arts and Sciences (BHAAAS). I joined the Board of Directors of this organization in 2014, served as its treasurer from 2015 to 2019, and as its president in 2021-22. I organized the 10th Annual Meeting of BHAAAS in October 2016 at Wellesley College.

I participated in the panel discussion Geography is history with panelists from USAID and the Bosnian Ministry of Human Rights and Refugees at the 14th Days of BHAAAS in Tuzla, Bosnia.

I was the lead organizer of the 13th Days of BHAAAS in Bosnia-Herzegovina that took place in Sarajevo, June 23-26, 2022. This was one of the largest scientific meeting in the Balkans, consisting of 32 symposia in a variety of disciplines, with 300 speakers from 22 countries. The overaching theme of the conference was sustainability. Here and here are a couple of my appearance on Bosnian television advertising the conference.

I coorganized the 12th Days of BHAAAS in Bosnia-Herzegovina that took place in Mostar, June 24-27, 2021 (originally scheduled for June '20 but postponed due to the pandemic).

I have been engaged in a number of STEM education initiatives in Bosnia-Herzegovina in recent years. Some of the talks I gave on this topic can be found on the talks page.

I was a member of the program committee for the Meditteranean Forum Data Science conference (MeFDATA2020) in October 2020.

I coorganized the 11th Days of BHAAAS in Bosnia-Herzegovina that took place in June 2019, in Sarajevo. I also organized a panel on STEM education in Bosnia-Herzegovina as part of the conference. Panelists included faculty from high schools and universities, parents, and representatives from NGOs and industry. Here is an article, and here and here are a couple of my appearances on Bosnian television (all in Bosnian), advertising the conference and the STEM panel, as well as discussing the education in Bosnia in general.

I coorganized the 10th Days of BHAAAS in Bosnia that took place in June 2018. I was the chair of the Symposium on Applied Mathematics and delivered several lectures at the conference (here is an article, in Bosnian, about some of the talks, including mine, and here and here are a couple of my appearances on Bosnian television advertising the conference).

In March 2019, I participated in the Transfer of Knowledge program run by the Diaspora Sector of the Bosnian Ministry of Human Rights and Refugees. I gave a number of lectures and talked to students about mentorship and opportunities in mathematics.

In spring 2018, I joined the Board of Directors of EDUS - Education For All. This wonderful organization provides assistance for education of children with developmental delays at preschool and elementary school level. Please consider supporting their important work.
