\textbf{Informal analysis seminar}\dotfill Feb.\ 2018\\ \hphantom{@}@ Kent State University, Kent, OH. \begin{itemize} \item Attended the lecture series: ``Packing a torus with circles'', ``Tensegrities: why things don't fall down'' and ``A degenerate isoperimetric problem in the plane with applications to a bi-stable Hamiltonian system''. \end{itemize} \textbf{Summer school on random graphs and probabilistic methods}\dotfill Jun.\ 2017\\ \hphantom{@}@ The Fields Institute, Toronto, CA. \begin{itemize} \item Attended a two week summer school comprised of four lecture series: ``Ten lectures on random graphs'', ``Ten lectures on random graph processes'', ``Random spanning trees and forests'' and ``Randomness for and against computation''. \end{itemize} \textbf{Graduate Research Workshop in Combinatorics (GRWC)}\dotfill Jun.\ 2015\\ \hphantom{@}@ Iowa State University, Ames, IA. \begin{itemize} \item Participated in an experimental research program for graduate students in discrete mathematics (see \url{https://sites.google.com/site/rmgpgrwc/}). The program consisted of about 35 graduate students in addition to faculty and postdocs working on problems presented by the students. Many collaborations have continued to be productive outside the workshop. \end{itemize} \textbf{Discrete Mathematics Working Seminar}\dotfill 2014--2015\\ \hphantom{@}@ Iowa State University, Ames, IA. \begin{itemize} \item Worked with a group of graduate students, postdocs and professors on research problems in discrete mathematics. This collaboration has resulted in the paper ``$(4,2)$-choosability of planar graphs with forbidden structures.'' \end{itemize} \textbf{Graduate Research Workshop in Combinatorics (GRWC)}\dotfill Jul.--Aug.\ 2014\\ \hphantom{@}@ University of Denver and University of Colorado Denver, Denver, CO. \begin{itemize} \item Participated in an experimental research program for graduate students in discrete mathematics (see \url{https://sites.google.com/site/rmgpgrwc/}). The program consisted of about 30 graduate students in addition to faculty and postdocs working on problems presented by the students. Many collaborations have continued to be productive outside the workshop. \end{itemize} \textbf{NSF REU}\dotfill Jun.--Aug.\ 2013\\ \hphantom{@}@ Iowa State University, Ames, IA. \begin{itemize} \item Worked under the direction of Sung-Yell Song on projects in algebraic graph theory, focusing on the classification of Cayley graphs and the construction of normally regular digraphs. \end{itemize}
