### Gavin Ball (UQAM-Montreal)

Gavin Ball was a PhD student in mathematics at Duke University, under the supervision of Robert Bryant. In his PhD research he used methods from the theory of exterior differential systems to study problems in differential geometry, and in particular problems related to special holonomy. He joined the collaboration in January 2017. In 2019, he became a postdoc at UQAM in Montreal.

### Michael Bell (Duke)

Michael Bell earned his PhD at Duke University under the supervision of Robert Bryant. His Ph.D. research concerned the geometry of partial differential equations and calibrated geometry, particularly in the special Lagrangian case. He had joined the collaboration in January 2018 and was awarded his degree in September 2019. He subsequently joined a tech startup firm in the Philadelphia area.

### Xuemiao Chen (Maryland)

Xuemiao joined the collaboration in June, 2017 as a Ph.D. student at Stony Brook University, under the supervision of Song Sun. In 2019, he became a postdoc at University of Maryland.

### Aleksander Doan (Columbia)

Aleksander Doan joined the collaboration in 2017 as a PhD student at Stony Brook University under the supervision of Simon Donaldson. In his PhD thesis, he studied generalized Seiberg-Witten equations and their relationship to gauge theory on manifolds with special holonomy. In 2019, he became a Postdoctoral Research Scientist at Columbia University and a Junior Research Fellow of Trinity College, University of Cambridge.

### Saman Habibi Esfahani (Stony Brook)

Saman Habibi Esfahani started his PhD at the Stony Brook University in 2017.

He is working under the supervision of Simon Donaldson. His research area

is gauge theory and manifolds with special holonomy.

### Nelvis Fornasin (Freiburg)

Nelvis Fornasin obtained his M.Sc. in the “Elite Master Course Theoretical and Mathematical Physics” at the LMU Munich. He joined the collaboration in October 2017 during his Ph.D. studies at the University of Freiburg, and left it in September 2019 after completing his degree. During this time he worked on the definition and computation of analytical invariants for Joyce G2 manifolds.

He is now pursuing a career in financial mathematics.

### Jacob Gross (Oxford)

Jacob Gross earned his PhD from Oxford University under the supervision of Dominic Joyce. He joined the collaboration in 2017. In his PhD thesis, he researched vertex algebra structures on the homology of moduli spaces. Jacob now works as a Quantitative Researcher at Radix Trading in Chicago.

### Alex Kinsella (UC Santa Barbara)

Alex Kinsella obtained his B.S. in Physics and Mathematics from Stanford University in 2015 and was subsequently a Ph.D. student in Physics at the University of California, Santa Barbara, under the supervision of David Morrison. He joined the collaboration in July, 2017, and completed his Ph.D. in June, 2021, following which he became a postdoctoral fellow at the Woods Hole Oceanographic Institute.

### Shan Zhou (UC Santa Barbara)

Shan Zhou is a Ph.D. student in physics at the University of California, Santa Barbara, under the supervision of David Morrison. He was a member of the collaboration from July 2019 through June 2021, but left the collaboration when his research interests within physics changed.
