Part 5. Raj talks to Gablehauser.

Raj: Good morning Professor Gablehauser, thank you for agreeing to see me.

Gablehauser: So how can I help you Dr. Koothrappali?

Raj: I have a suggestion for something that could help the Caltech Physics department but I must also state at the start that there are personal reasons for this as well. I did my first degree at Delhi University back home in India before I went off to do my doctorate in Cambridge and then I came here to Caltech. Professor Malik runs a research group in Delhi doing laser research similar to what Dr. Hofstadter does here in at Caltech. Professor Malik's most recent papers have all cited Leonard, I mean Dr. Hofstadter's work. I think that a research collaboration between Caltech and Delhi could be useful.

Gablehauser: Is this Professor Prakash Malik in Delhi?

Raj: Yes, do you know him?

Gablehauser: We were Ph.D students together in Chicago 20 years ago, a good guy and good scientist. So what is the personal connection, you are an Astrophysicist, you don't work with lasers.

Raj: Dr. Leonard Hofstadter is currently in a relationship with my sister Priya, she is a lawyer. In 5 months time Priya will have to return to Delhi to spend 6 months working at home before she can return to California.

Gablehauser: So you are trying to help your sister by arranging a trip to India for Dr. Hofstadter. Well I can't promise anything but I will contact Professor Malik to see if he can accept a visiting scientist. It would be good for Dr. Hofstadter to have some experience working outside the USA.
