Marjorie Hahn

Marjorie "Molly" Greene Hahn (born December 30, 1948) is an American mathematician and tennis player. In mathematics and mathematical statistics she is known for her research in probability theory, including work on central limit theorems, stochastic processes, and stochastic differential equations. She is a professor emeritus of mathematics at Tufts University.[1]

Education

Molly Greene did her undergraduate studies at Stanford University, graduating in 1971.[1] She went on to graduate study at the Massachusetts Institute of Technology, and married Peter Florin Hahn in 1973. Like Greene, Peter Hahn had graduated with great distinction from Stanford in 1971;[2] he was a graduate student in mathematics at Harvard University,[3] and went on to a career in radiology at Harvard.[4]

Marjorie Hahn completed her Ph.D. in 1975. Her dissertation, supervised by Richard M. Dudley, was Central Limit Theorems for D[0,1]-Valued Random Variables.[1][5]

Academic career

After postdoctoral study at the University of California, Berkeley, Hahn became a faculty member at Tufts University in 1977.[1] While active at Tufts, she supervised the dissertations of 16 doctoral students, more than anyone else in the department.[1][5] She retired as professor emeritus in 2016.[1][6]

In 1985, Hahn was elected as a Fellow of the Institute of Mathematical Statistics.[1][7]

Tennis

Hahn is also a tennis player. She played on the Stanford team from 1967 to 1971,[8] and passed up a chance to play tennis professionally in favor of her work in mathematics.[1] In 2006 her name was added to the United States Tennis Association New England Hall of Fame.[1]

In 2008 she represented the U.S. in an international seniors competition, the Alice Marble Cup,[8][9] where she helped her team win a silver medal.[8] In 2017 she was part of a U.S. team that won the Kitty Godfrey Cup for women 65 or over at the International Tennis Federation World Super-Senior team championships.[10]

Comparing mathematics with tennis, Hahn has said "In mathematics, you try to prove things step by step; you attempt to set up a logical method. I approach tennis by using this plan and then adjust on the fly."[9]

gollark: The 350M one doesn't seem to exist and I can't really work with anything bigger.
gollark: This is annoying, apparently 6GB of VRAM isn't enough to finetune the 125M GPT-Neo even with a batch size of 1. I might just use Colab.
gollark: Geese are fearsome beings.
gollark: It would take ages to download so I'd prefer not to if it probably won't work.
gollark: Speaking of somewhat underpowered hardware, can I use the 2.7B GPT-Neo model on my RTX 2060 (6GB VRAM) in half precision? Multiplication leads me to think it's possible just considering the parameters, but some internet things imply it won't work presumably because of storing other stuff.
