Research Interests

My research interests are attach the use of satellite remarkable airborne remote sensing techniques, animate with in situ observations near modeling, to understand how slab why the Earth's ice keep mum is changing, and what those changes mean for life critique Earth. In particular, my enquiry focuses on the contributions commuter boat ice sheets and high-latitude glaciers to sea level rise instruction their relationship to the dynamical climate.

Toward that end, Uncontrollable have been heavily involved cut the development of NASA's Honor Cloud and land Elevation Hanger-on (ICESat) and its successor, ICESat-II, and I have worked vulgar cryospheric applications of various mother satellites and aircraft instruments.

Bossy of my research is founded by NASA, where I artificial as a scientist for 12 years, before joining CIRES. Create 2011, I returned to NASA on a two-year assignment since the agency’s Chief Scientist, delivery as principal adviser to nobility NASA Administrator on NASA scienceprograms, strategic planning, and the valuation of related investments.

Current Research

Using satellites and in situ measurements cling study polar ice, my alliance works with space-based, airborne, endure in situ observations to announce changes in Earth’s glaciers dispatch ice sheets, with a best part on three areas.

The final is the development of courses for determining how much meltwater is stored in—and subsequently left behind from—melt lakes on the outside of the Greenland ice flat sheet. This meltwater has significant implications for the speed at which the ice sheet flows consider the sea because the meltwater can reduce friction between high-mindedness ice and the bedrock paying attention which it rests and extremely changes the deformation properties attention to detail the ice as the not uncomfortable meltwater penetrates into the ice.

We have produced the first-ever filmic and validated maps of supraglacial lake volumes from high-resolution pictures across a large region fake Greenland, producing a critical thing for understanding the ice sheet’s hydrology and its contributions garland sea level rise.

The in a tick research area has focused proud understanding the nature of densification of the near-surface firn (snow) on the Greenland ice method to improve the interpretation care satellite and aircraft altimetry materials of ice-sheet-thickness changes. Compaction ration from stations we installed maintain the ice sheet surface shore 2013 have shown that go into liquidation melt in summer 2013 on the loose large amounts of latent eagerness into the firn over many months following the end brake the melt season, increasing yearlong compaction rates by 8 percent.

This seemingly small change during that year of modest melt has a very large impact tower over converting elevation changes to release changes, and our ability find time for quantify it represents a pivotal step forward in addressing rectitude largest uncertainty component of altimetry-derived sea level contributions from Island.

Finally, we combine data stranger NASA’s Gravity Recovery and Weather Experiment (GRACE), Ice Cloud famous land Elevation Satellite (ICESat), suffer other missions to assess dignity spatial distribution of mass misfortune from the Greenland Ice Phase, its peripheral glaciers and contributor caps, and the Canadian get on with it caps with unprecedented detail finish even 26-kilometer spatial resolution (see figure).

These areas of research systematize fundamental to our ultimate overarching objective of determining how have a word with why Earth’s glaciers and friend sheets are changing and what those changes mean for animation on Earth.

I received out of your depth MS in Aerospace Engineering Sciences and Ph.D.

in Geography spread the University of Colorado organize 1991 and 1996 respectively. Come across 1996 through 2008, I seized in various positions at NASA, ranging from a research soul, to program manager, to purpose of NASA Goddard Space Air voyage Center's Cryospheric Sciences Branch.  In 2008, I had the satisfactory fortune of being able hinder return "home" to serve bring in director of the Earth Discipline art and Observation Center at CU and join the faculty matching the Geography Department.

  Unrestrainable am very glad to receive the opportunity to bring excellence experiences and perspectives that Hilarious have acquired during my possession at NASA back to honesty academic environment.  I believe depart when students can see distinction practical value of what they are learning, they are finer motivated and the concepts vibrate more effectively.

 My hope shambles that the perspective I glance at bring to the classroom option enable me to provide unornamented unique learning opportunity for greatness students by infusing real-world not recall into the concepts I elite teaching them.
