1 %{pagebegin} 2 <article> 3 <h1>Research</h1> 4 5 <p>I am interested in understanding mechanical and hydrological processes in the 6 climate system, specifically processes that relate to mechanics of granular 7 materials, sea ice, and ice-sheet flow under past, present, and future scenarios. 8 Investigations of fundamental granular mechanics are important in many 9 geodynamical and geomorphological processes and settings, such as earthquakes, 10 landslides, sediment transport in flowing water, and dam stability.</p> 11 12 <p>I have listed my publications and submitted manuscripts below. 13 If you would like to collaborate on a scientific problem please <a 14 href="contact.html">get in touch</a>.</p> 15 16 17 <h2>Publications</h2> 18 19 <ul> 20 21 <li> 22 L.
