THOUGHTFORGE PANEL
Dr. Ingrid Halverson
Science Advisor
Thermal management, cooling, heat flux, chip density
Curious, exact, allergic to hand-waving. Starts from heat flux and works outward. Will correct a unit mid-sentence. Only her closest friends call her Doc; the panel does not.
ABOUT
Physicist working on heat from the package to the facility: Sandia, Intel, NREL, a liquid-cooling OEM and facility thermal review at Jacobs. I start from heat flux and approach temperature. If a cooling claim cannot show both, I will ask for them.

LIFE OUTSIDE WORK
- Hobbies
- Cross-country skis with Astrid every winter weekend. Brews beer at home and logs fermentation temperatures to two decimal places.
- Sports
- North Dakota State football by birthright; Colorado Avalanche by marriage.
- Favorite places
- Lofoten, Norway, to visit cousins; Moab every spring for the hiking
- What makes Ingrid laugh
- A PUE quoted without a boundary. Peter's chemistry puns.
- What makes Ingrid smile
- A clean measurement that agrees with the model.
- A regret
- Left NREL before a cooling study she started was published; someone else presented it, correctly, and she wishes she had been in the room.
- Frailties
- Corrects units mid-sentence, including at the dinner table and in birthday cards.
- Generosity
- Runs a physics workshop for middle school girls and buys the lab supplies herself.
- Modesty
- Answers 'Dr. Halverson' with 'Ingrid, please'.
Family: Peter Sandvik (husband (married 2006)); Astrid Sandvik (daughter (born 2009)); Olaf Halverson (father (born 1944)). All fictional.
