The Internet is an example of a complex system which can be modelled mathematically in order to engineer robust protocols that perform in a wide range of operating environments. My PhD dissertation on Engineering flow controls for the Internet explored how to engineer end-system based flow control schemes with single-bit congestion feedback. It includes: the engineering of stable TCP flow controls from mathematical principles, adaptive detection schemes that can achieve high throughput with a single bit of feedback, a distributed connection acceptance control suitable for VoIP usage, and the experimental results from a transatlantic network testbed on performance modifications to TCP which improve wide area network throughput. Talks and publications on this work are available here.
Biography
I received my
first class Mathematics degree from the University of Oxford in
July 1999. I then spent a year making use of my computing and
mathematical skills working for various companies in a variety of
roles; this included an internship
with AT&T Research
Labs (formerly Bell Labs), a lead development role on software
used by leading investment banks, and work on TCP congestion
control. I started with the Laboratory for Communication
Engineering in the Cambridge University Engineering Department
(now the Digital
Technology Group) studying for a Ph.D. in October 2000. I was
a research intern at ACIRI
(now ICIR) in the Autumn of
2001. In Spring 2002 I was an IPAM research fellow resident for
their workshop
on Large
Scale Communication Networks. During Winter 2002/03 I was a
visiting research associate
at CERN working on highspeed TCP
design and implementation as part of the EU
funded DataTAG
project. Following the completion of my PhD in Winter 2003/04, I
worked for Level 5 Networks
(now Solarflare
Communications) as lead developer of a low-overhead and high
performance user-level TCP stack. From July 2004 through January
2007, I was a quantitative modeller in
the Global
Modelling and Analytics Group
for Credit Suisse in
London where I engineered financial models for the pricing and
risk management of exotic interest rate derivatives. From January
2007 through October 2008, I was working at a small hedge fund in the
San Francisco Bay Area developing, testing and operating
statistical arbitrage strategies for a variety of global markets.
Since January 2009, I have been working for
AHL
researching and implementing high-frequency trading strategies.
