Key Note © Kay Herschelmann/BMSOn Friday 20 October 2017, in collaboration with Geo.X the Research Network for Geosciences in Berlin and Potsdam, the BMS jointly held a “Career Day 2017: Scientific Life Balance” with twelve other graduate programs at the Urania in Berlin. This event about the art of work-life balance in scientific research was attended by over 100 registered participants.

The keynote speech on striving for balance in scientific life was followed by an open space session hosted by ten female and male researchers, professors and professionals. The hosts shared their work and life experiences in an open “marketplace-style” setting in which the participants were able to move between ten booths and gain a variety of information and ideas by engaging in each discussion at hand. Host sharing work and life experiences with PhD students © Kay Herschelmann/BMSThe topics at each booth ranged from how to develop effective time management strategies, or find a good job in the private sector, to the issues couples face such as finding a job in the same city, or how scientists with families achieve work-life balance at home or abroad.

 In the afternoon, there was a podium discussion with experts and decision-makers, who are active in the areas of science policy and research funding, and come from both the private and the academic sector. The aim was to provide an opportunity for additional discussion and suggestions at a more general level.

The overall goal of this event was to assist all female and male students and researchers at all scientific career levels to gain insight into the tried and tested ways of achieving a work-life balance. Working alongside the Berlin Mathematical School to bring this very successful event into being were two collaborative research centers CRC 1114 and CRC 1294, the graduate research school GeoSim, two research training groups BioMove and NatRiskChange, two European training networks SUBITOP and SystemRisk, two initial training networks IsoNose and ALErT, the international research training group StRATEGy, the integrative research institute IRI THESys and Geo.X Young Academy.

In their rich, diverse and international mathematical environments, the Berlin Mathematical School (BMS) and the Barcelona Graduate School of Mathematics (BGSMath) share the common goal of striving for excellence in their doctoral and postdoctoral training programs. To kick off the new collaboration between these two graduate schools, the first BMS - BGSMath Junior Meeting was held in Barcelona on 9 and 10 October 2017.

The aim of this meeting was to bring together young researchers from the two cities, and the organizing committee was made up of PhD students and postdocs from both the BMS and BGSMath. In total there were 71 registered participants, 20 of whom were affiliated with Berlin universities and included 16 members of the BMS student body and postdoctoral faculty. The meeting was opened by the BMS Deputy Chair Prof. John M. Sullivan and the BGSMath Director Prof. Marc Noy, and was divided into three sections: Algebra & Geometry; Discrete Mathematics & Computer Science; and Probability, Statistics & PDEs. Each section consisted of one keynote address by a senior researcher and eight short talks by PhD students and postdocs from both the Berlin and the Barcelona side.

The BMS and BGSMath have declared their intention to cooperate together in initiatives aimed at promoting the mobility of and exchange between students and faculty members by way of events such as the Junior Meeting; joint summer schools; mutual visits by advanced students and postdocs of each institution; and other scientific activities. The ultimate goal is to create strong scientific exchange, strengthen research collaboration between the respective math communities, and enhance the multicultural environment of both graduate schools.

The BMS would like to thank Bahareh Banyassady, Katharina Klost, Jean-Philippe Labbé and Martin Wahl for their hard work and commitment in getting the first BMS joint event with BGSMath off the ground!

Martin Skrodzki © Tsutomu ArakiMartin Skrodzki, BMS Phase II student and member of the FU Berlin’s Mathematical Geometry Processing group, was part of the winning team in the FU Berlin’s "Research to Market Challenge 2017". His team, Double Cover, was awarded first prize in the category “Cultural & Social” for its business model to make artistic and aesthetic geometric models available for education.

Created using sturdy, metallic-looking paper, the cut-outs for the models can be produced in large numbers using a laser cutting technique. The models are then put together by the users themselves and depict mathematical geometries with so-called multiple coverings. These are geometric analogies to the weaving process used in the production of cloth. By introducing multi-coverings, the models become both more stable and mathematically interesting. The models presented depict platonic solids, double covered, but the method can be applied to any geometrical model. Potential customers for Double Cover’s winning idea include teachers, science workshop organizers and private individuals. The other team members are the former BMS vice chair and head of the Mathematical Geometry Processing group Prof. Dr. Konrad Polthier, technical staff member Ulrich Reitebuch and student assistant Kevin Guo.

The “Research to Market Challenge” is a competition for research-based product and business ideas and is open to members or alumni of the FU Berlin, among others. As well as prize money in the sum of 1500 euros, the team has been offered the chance to take part in a one-day workshop on business model development, coaching on how to successfully present their idea, and personal feedback by experts.

No sooner had Martin accepted this prize with his team on 18 July 2017, than he and some members of his research group were awarded with another prize! On 10 August 2017 in Tokyo, Japan, the winners of this year’s Asian Digital Modeling Contest (ADMC) were announced: Martin, Konrad, and Ulrich were jointly awarded one of the two ADMC2017 Awards for Excellence for their model “Chladni Towers”.

Martin Skrodzki about Chladni Towers © Tsutomu ArakiThe aim of the ADMC is to encourage the creation of three-dimensional mechanisms and objects in innovative environments via 3D printing technology. The competitors were asked to submit an original design that could be created using a 3D printer. Out of 27 competitors, eleven finalists were invited to present their designs at the 2017 Asian Forum on Graphic Science in Tokyo. Upon announcing “Chladni Towers” as one of the winning designs, the jury explained its choice: "The form is constructed from a layered Chladni figure, which is derived from physical phenomena. Visualization of sound is often performed by two-dimensional figures, but by using a layered structure, additional dimension is expressed in the height direction and the vibration of sound is expressed in a 3D space. The idea is novel and the realized form is elegant. This is a splendid work that visualizes invisible physical phenomena.”

As a member of the Mathematical Geometry Processing group at the FU Berlin, Martin is currently working on his PhD under the supervision of the former BMS vice chair Prof. Dr. Konrad Polthier. Martin's research interests include the acquisition of point sets via 3D-scanning as well as their processing. With regards to efficiency, he is interested in nearest-neighbor algorithms and corresponding data structures.

Many congratulations to Martin and the other members of his team for their success!

Each semester, the BMS designates one of the BMS Friday Colloquia as the Sonia Kovalevskaya Colloquium. This lecture, named after the pioneering Russian mathematician, features female mathematicians, both senior and junior, who are regarded as successful role models. The BMS Kovalevskaya Lunch takes place prior to the main lecture and is an event held exclusively for women at the BMS.

On 2 June 2017, the 20th BMS Kovalevskaya Lunch took place with Prof. Sujatha Ramdorai as the twentieth special guest invited to share her experience as a woman mathematician with twenty participants from the BMS. In celebration of this milestone, everyone in attendance was given a small gift from the BMS in the form of a USB stick. 

Sujatha Ramdorai is an algebraic number theorist and, over lunch at the Urania Berlin, she shared the story of her desire to study mathematics and outlined her career success to date, which includes being a member of the Scientific Advisory Council to the Prime Minister of India for a period of five years. Sujatha is currently a professor of mathematics at the University of British Columbia in Canada. 

The BMS Kovalevskaya Lunch, held once a semester since 2007, aims to give female students the opportunity to talk to an outstanding female mathematician and to exchange experiences as women in the field of mathematics. At this informal event, students have the chance to discuss the issues that directly impact female mathematicians and their careers, such as job opportunities, parenthood and work-life balance. Phase I student Yingying, who took part in the Kovalevskaya Lunch for the first time, said that the meeting with Sujatha gave her more motivation to continue doing mathematics and to contribute to the support of women in this field. She added that she was grateful to have been given the chance to meet Sujatha in person. 

Previous Sonia Kovalevskaya Colloquium guest speakers can be found on this page of our website.

The BMS is committed to providing an outstanding environment where women are able to thrive in mathematics. In 2016, the BMS student body was over 30% female, but the goal of the BMS is to achieve a 50% representation of women among its students. As well as the Kovalevskaya Lunch event, the BMS strives to provide positive role models for women via the BMS faculty and postdoc faculty members, BMS mentors, board members, guest speakers and visitors too. In addition, the BMS awards the Hilda Geiringer Scholarship to outstanding female PhD students in recognition of their achievements to date and to support their future mathematical research endeavours. Hilda Geiringer’s daughter, Magda Tisza, validated the efforts of the BMS in fostering women mathematicians with her comment: "The stellar record of some of your scholarship selections is impressive."

On Tuesday 23 May 2017, the BMS welcomed a delegation of 20 undergraduate students and three faculty members from Morehouse College and Spelman College, two American universities situated in Atlanta, Georgia. This event aimed to give the visiting students and faculty a chance to connect with their counterparts in Germany, and gain first-hand exposure to prospective careers and research opportunities in the field of mathematics.

BMS Deputy Chair, Prof. Dr. John Sullivan, began by giving a presentation about the BMS, its PhD Program, and about the mathematics landscape in Berlin in general. This was followed by talks from three BMS Phase II students, who each presented their own research projects. Patrick Gelß, based at the FU, gave a talk on “The tensor-train format and its applications - Modeling and analysis of chemical reaction networks, catalytic processes, fluid flows, and Brownian dynamics”. Ana Djurdjevac, also based at the FU, presented her research on “Random PDEs on evolving hypersurfaces”. Finally, using material from his PhD project, Carlos Echeverría Serur, based at the TU, gave a talk entitled “On the solution of linear systems arising from Shishkin mesh discretizations”. Carlos said he hopes that all the talks will encourage some of the American students to come to Berlin for their graduate studies.

Following the BMS presentations, the delegation then visited the TU Berlin's 3D LAB. Afterwards, the American students and faculty were given the chance to interact informally with BMS students, faculty and staff over lunch in the BMS Lounge.

This event was part of the STEM LAUNCH Study Tour of Germany organized by Cultural Vistas, a non-profit organization that facilitates connections between American and international students, academics and professionals. Through a two-week professional and cultural tour of Berlin and Munich, this study tour aims to encourage students from Georgia-based historically black colleges & universities to consider adding an international context to their educational and career paths.
