Research and career

Between 2012 and 2014 Bah was a postdoctoral researcher at the École Polytechnique Fédérale de Lausanne, where he continued his investigations into compressed sensing. He was a member of the Laboratory for Information and Inference Systems.{{Cite journal|date=2016-01-09|title=Dr Bubacarr Bah elected Humbolt [sic] Chair Faculty at AIMS South Africa|url=https://actu.epfl.ch/news/dr-bubacarr-bah-elected-humbolt-chair-faculty-at-a/|language=en|website=actu.epfl.ch}}

In 2014 Bah joined the University of Texas at Austin, where he worked on signal processing, machine learning and sampling strategies in high-dimensional data.{{Cite web|url=https://www.nexteinstein.org/blog/2016/08/31/bubacarr-bah-has-been-awarded-the-prestigious-german-chair-in-mathematics/?platform=hootsuite|title=Bubacarr Bah Has Been Awarded the Prestigious German Chair in Mathematics {{!}} AIMS|website=nexteinstein.org|access-date=2019-03-26}} He developed a matrix for dimensionality reduction that uses bi-Lipschitz embeddings, which can exploit data redundancy.{{Cite web|url=https://www.colorado.edu/amath/events/Computational-Math-Seminar-Bubacarr-Bah|title=Computational Math Seminar: Bubacarr Bah|date=2015-10-06|website=colorado.edu|language=en|access-date=2019-03-26}}{{Cite web|url=https://aims-cameroon.org/2016/06/17/visiting-delegation-from-the-alexander-von-humboldt-foundation/|website=aims-cameroon.org|title=Visiting delegation from the Alexander von Humboldt Foundation {{!}} AIMS Cameroon - NextEinstein Initiative|language=en-US|access-date=2019-03-26}}{{Cite journal|last1=Bah|first1=Bubacarr|last2=Sadeghian|first2=Ali|last3=Cevher|first3=Volkan|date=2013|title=Energy-aware adaptive bi-Lipschitz embeddings|arxiv=1307.3457}}

In 2016 Bah was appointed the German Chair in Mathematics at the African Institute for Mathematical Sciences (AIMS), which is supported by the Humboldt Foundation. The position was welcomed by the AIMS community, who believe Africa needs better data science infrastructure. Bah organised the software engineering for Applied Mathematical Sciences workshop, which teaches basic programming and research programming.{{Cite web|url=https://seams-workshop.gitlab.io/faculty/|title=SEAMS Workshop v5 ~ TBD 2019!|website=seams-workshop.gitlab.io|access-date=2019-03-26}}{{Cite web|url=https://www.nexteinstein.org/blog/2017/06/02/aims-south-africa-data-science-workshop-organised-by-dr-bubacarr-bah-the-german-research-chair-of-mathematics/|title=AIMS South Africa : Data Science Workshop organised by Dr Bubacarr Bah, the German Research Chair of Mathematics {{!}} AIMS|website=nexteinstein.org|access-date=2019-03-26}} He is responsible for connecting the AIMS in South Africa with central Africa and German universities.{{Cite web|url=https://www.humboldt-foundation.de/web/45078366.html|title=Humboldt Foundation strengthens university education and research in mathematics in Africa|website=humboldt-foundation.de|access-date=2019-03-26}} As of 2019, the Alexander von Humboldt Foundation supports five chairs at AIMS centres.{{Cite web|url=https://www.humboldt-foundation.de/web/54057910.html|title=New research chair appointed in Africa|website=humboldt-foundation.de|access-date=2019-03-26}} He holds a joint position at Stellenbosch University, where he works on information theory and deep learning.{{Cite web|url=http://sanum.github.io/|title=SANUM - South African Numerical and Applied Mathematics|website=sanum.github.io|access-date=2019-03-26}}{{Cite web|url=http://newton.cam.ac.uk/person/isaac-id-21837|title=Bubacarr Bah {{!}} Isaac Newton Institute for Mathematical Sciences|website=newton.cam.ac.uk|access-date=2019-03-26}}

In March 2019 Bah was appointed to the Google advanced technology external advisory council, a collection of experts who will consider the artificial intelligence (AI) principles of Google.{{Cite web|url=https://www.blog.google/technology/ai/external-advisory-council-help-advance-responsible-development-ai/|title=An external advisory council to help advance the responsible development of AI|date=2019-03-26|website=blog.google|language=en|access-date=2019-03-26}}

Google disbanded ATEAC on April 4, 2019 following criticism by Google employees about another member, Kay Coles James.{{cite web|url=https://blog.google/technology/ai/external-advisory-council-help-advance-responsible-development-ai/|title=Google updated news release|accessdate=9 July 2024}}
