허준이 교수 연구 결과가 어떻게 실생활에 응용이 되나요?
이번에 필즈상을 받은 허준이 교수의 업적이 어떻게 실생활이나 산업에 응용되는지 궁금해하시는 분들이 있어서 질문도 종종 받게 되네요. 순수수학 하는 사람들은 원래 흥미로운 수학적 현상의 본질적인 원리를 규명하려는 호기심으로 연구를 하기 때문에 응용 가능성을 생각하고 연구를 하는 것도 아니고 실제 응용이 되더라도 연구자 본인이 자기 연구가 어떻게 응용되는지 모를 수도 있습니다. 그렇지만 수학이라는 것이 활용이 되면 정말 파급이 큽니다. 우리가 이 글을 보기 위하여 인터넷을 접속할때부터 이 글을 읽을 때까지 정말 여러 곳에서 수학이 활용되고 있다고 할 수 있습니다. 아울러 수학은 오랜 시간이 지나 활용되는 사례도 여럿 있구요. 그러다보니 수학자들에게 이런 질문을 하면 100년이 지나면 사용될지도 모른다 같은 식의 모호한 답을 하기 마련인데 기자분들은 이런 답을 들으면 답답하실 거에요. 수학자들은 틀린 답은 안 하도록 직업적 훈련을 받는 사람들이라 아닌 걸 맞다라고 하진 못하거든요.
칠판 강연을 위한 연사 추적 카메라 설치 및 유튜브 생중계 경험담
코로나19 이후 세미나 및 강연을 온라인으로 중계하거나 동영상을 녹화하려는 수요가 많아졌습니다. IBS 이산수학그룹에서는 2018년 12월 시작할 때부터 세미나실에 연사 추적 카메라를 설치하여 동영상을 녹화하여 YouTube에 공개해왔고, 2020년 3월부터는 YouTube Live를 통하여 실시간 중계도 해왔습니다. 하지만 2018년에 만든 세팅에 화질, 음질 등 여러 가지 불만도 있어서 어떻게 개선해야 할지 고민이 많았는데 2022년 봄에 이사를 하게 되면서 새롭게 세미나실 셋업을 할 수 있는 기회가 생겨서 훨씬 더 좋은 셋팅을 할 수 있게 되어서 그 사항을 공유해드리고자 합니다.
Virtual ICM 2022 Invited talks in Combinatorics
For convenience, I’ve collected the list of invited speakers for Section 13 Combinatorics at the Virtual ICM 2022 and the schedule of their talks.

PhD position in Extremal and Probabilistic Combinatorics at Umeå University, Sweden
I am sharing the following message received by email. The application deadline is March 11, 2022. I am advertising a PhD position in extremal and probabilistic combinatorics, see the link below: https://umu.varbi.com/en/what:job/jobID:467679/ . I would be most grateful if you could forward this link to any master’s students of yours at KAIST who may be interested. Our combinatorics group has been rather fortunate in recruitment of late — Klas Markström and I have been joined by Maryam Sharifzadeh, Klara Stokes and István Tomon in the past two years — so we can hopefully offer an attractive environment for a PhD student (as well as fun research problems).
Postdoc in Discrete Math at Illinois Tech
I’m sharing a message from Hemanshu Kaul at Illinois Tech. We are hiring a postdoc in Discrete Math at IIT (Illinois Tech) to start in Fall 2022. It is a one year position followed by one year extension subject to performance review and funding. In the past every such position has been extended for the second year. We are interested in candidates with broad research interests in discrete mathematics and its applications. In particular, we are interested in all aspects of graph theory: extremal, enumerative, topological, and spectral; and algorithms and models in network and discrete optimization. Connections to machine learning, graph neural nets, and related computational fields are a plus.
Hong Liu is moving to IBS as a Chief Investigator to start the IBS Extremal Combinatorics and Probability Group (ECOPRO) on April 2022 and is hiring up to 5 postdocs (Application Deadline: January 14, 2022)
News: The Institute for Basic Science (IBS) in Korea is expanding further into discrete mathematics by establishing a new “IBS Extremal Combinatorics and Probability Group (ECOPRO)” led by Hong Liu from the University of Warwick, UK on April 2022.

수학동아xIBS, 나의 삶 나의 수학 시리즈 인터뷰+기고
수학동아와 기초과학연구원(IBS)이 설립 10주년을 맞아 공동으로 IBS 내의 수학자들의 연구와 삶을 소개하는 시리즈를 시작하였습니다. 제 이야기로 그 시리즈 시작이 되었습니다. 내용은 수학동아 2021년 5월호나 IBS 홈페이지에서 볼 수 있습니다. 글을 다듬어주신 홍아름 수학동아 기자님, 그리고 멋진 사진을 찍어주신 AZA 스튜디오 남윤중 실장님 감사드립니다. 내용은 아래에서 볼 수 있습니다. 1편: 기자의 인터뷰 2편: 연구 경험담 제가 하던 수학 연구는 길게는 수년, 짧게는 수일 만에 완성되기도 했습니다. 그중 독일의 한 소도시에서 했던 연구는 단 하루 만에 답을 얻었습니다. 그래프 알고리듬 분야에서 유명한 브루노 쿠르셀 프랑스 보르도컴퓨터과학연구소(LaBRI) 교수님과 만났던 2004년 5월에 생긴 일입니다…
