The Long Arc of Science

Using examples from my own astrophysics research career as well as modern science more generally, I will discuss how ideas in science evolve, the importance of persistence, and the necessity for humility when using current scientific knowledge to influence public policy.

Challenges in RF Integrated Circuits

The first part of this presentation will give a brief overview of my research on Radio Frequency Integrated Transceiver Circuits. The presentation will focus on the challenges for integrated wireless transceivers for bio-medical applications, STAR (simultaneous transmit and receive ), and supply modulated transceivers.

Balancing the World's Carbon Budget

The recent meeting in Paris on climate change ended with a challenge to all the countries of the world: do not settle for a global warming of 2°C, but aim for a much more ambitious goal of 1.5°C.  Scenarios based on either target require taking carbon dioxide already emitted back from the environment and dispose of it safely and permanently in order to create net negative carbon dioxide emissions.

The 2010-2011 Canterbury Earthquake Sequence: From Paleoseismology to Policy

The 2010-2011 Canterbury earthquake sequence (CES), including the moment magnitude (Mw) 7.1 Darfield earthquake and Mw 6.2, 6.0, 5.9, and 5.8 aftershocks, occurred on a suite of previously unidentified, primarily blind, active faults, and is one of Earth's best recorded historical earthquake sequences.
