    <h2>Short Bio</h2>
    <p>
        I joined the <a href="https://compsec.epfl.ch" target="_blank" rel="noopener noreferrer">Laboratory for Computation Security</a> at <a href="https://www.epfl.ch" target="_blank" rel="noopener noreferrer">EPFL</a> as a cryptography engineer in fall of 2023; my work is advised by <a href="https://ic-people.epfl.ch/~achiesa" target="_blank" rel="noopener noreferrer">Alessandro Chiesa</a>.
    </p>
    <p>
        Before that, I completed graduate coursework in computer science at <a href="https://www.nyu.edu" target="_blank" rel="noopener noreferrer">NYU</a> and was a research assistant for <a href="https://jbonneau.com" target="_blank" rel="noopener noreferrer">Joseph Bonneau</a>.
    </p>
    <p>
        During this time, I was also a software engineer at <a href="https://www.ibm.com/us-en" target="_blank" rel="noopener noreferrer">IBM</a> in New York City.
    </p>
    <p>
        For two amazing winters, I lived in the <a href="https://g.co/kgs/yB1Fzef" target="_blank" rel="noopener noreferrer">Eastern Sierra</a> of California between <a href="https://g.co/kgs/yUphB9r" target="_blank" rel="noopener noreferrer">Mammoth Lakes</a> and <a href="https://g.co/kgs/oPYfvGG" target="_blank" rel="noopener noreferrer">Bishop</a>.
    </p>
    <p>
        Before that, I was a software engineer at the telehealth startup <a href="https://www.talkspace.com" target="_blank" rel="noopener noreferrer">Talkspace</a>.
    </p>
    <p>
        I earned my B.A. in <a href="https://cs.nyu.edu/home/index.html" target="_blank" rel="noopener noreferrer">Computer Science</a> from NYU in 2013. Outside of class, I ran for the varsity cross country and track <a href="https://gonyuathletics.com/sports/mens-cross-country" target="_blank" rel="noopener noreferrer">teams</a> at NYU.
    </p>
    <p>
        Before NYC, I grew up in <a href="https://g.co/kgs/8YPkJxf" target="_blank" rel="noopener noreferrer">Ventura</a>, California, where I was born in 1990. I attended Foothill Technology High School.
    </p>
    <p>
        I enjoy skiing and <a href="/images/kalymYES.jpg" target="_blank" rel="noopener noreferrer">📷 rock climbing</a> very much. I also enjoy cooking shows and guitar.
