systems, and machine learning.</span></font></p><font face="arial, sans-serif"><br style="color:rgb(0,0,0)"></font><p dir="ltr" style="color:rgb(0,0,0);line-height:1.38;text-align:justify;margin-top:0pt;margin-bottom:0pt"><font face="arial, sans-serif"><span style="font-weight:700;font-variant-ligatures:normal;font-variant-alternates:normal;font-variant-numeric:normal;font-variant-east-asian:normal;vertical-align:baseline;white-space:pre-wrap">Bio: </span><span style="color:rgb(34,34,34);font-variant-ligatures:normal;font-variant-alternates:normal;font-variant-numeric:normal;font-variant-east-asian:normal;vertical-align:baseline;white-space:pre-wrap">- Undergraduate and Masters in Math at Uni of Cambridge</span></font></p><p dir="ltr" style="color:rgb(0,0,0);line-height:1.38;margin-top:0pt;margin-bottom:0pt"><span style="color:rgb(34,34,34);font-variant-ligatures:normal;font-variant-alternates:normal;font-variant-numeric:normal;font-variant-east-asian:normal;vertical-align:baseline;white-space:pre-wrap"><font face="arial, sans-serif">- PhD in Applied math from University of Waterloo</font></span></p><p dir="ltr" style="color:rgb(0,0,0);line-height:1.38;margin-top:0pt;margin-bottom:0pt"><span style="color:rgb(34,34,34);font-variant-ligatures:normal;font-variant-alternates:normal;font-variant-numeric:normal;font-variant-east-asian:normal;vertical-align:baseline;white-space:pre-wrap"><font face="arial, sans-serif">- Postdoc at McGill in Dept. of Physiology where I worked with experimentalists and clinicians to study the nonlinear dynamics of cardiac arrhythmia.</font></span></p><p dir="ltr" style="color:rgb(0,0,0);line-height:1.38;margin-top:0pt;margin-bottom:0pt"><span style="color:rgb(34,34,34);font-variant-ligatures:normal;font-variant-alternates:normal;font-variant-numeric:normal;font-variant-east-asian:normal;vertical-align:baseline;white-space:pre-wrap"><font face="arial, sans-serif">- Joined UCR as an Assistant Prof in the Math dept. at beginning of January</font></span></p></div><div><font face="arial, sans-serif"><br></font></div><div><font face="arial, sans-serif"><br></font></div><div><font face="arial, sans-serif"><br></font></div><font face="arial, sans-serif"><span class="gmail_signature_prefix">-- </span><br></font><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><font face="arial, sans-serif"><span style="color:rgb(34,34,34)">Qixuan Wang</span><br></font></div><div style="color:rgb(34,34,34)"><font face="arial, sans-serif">Associate Professor</font></div><span style="color:rgb(34,34,34)"><font face="arial, sans-serif"><div>Department of Mathematics</div><div>Interdisciplinary Center for Quantitative Modeling in Biology</div></font></span><div style="color:rgb(34,34,34)"><font face="arial, sans-serif">Biophysics Graduate Program</font></div><div style="color:rgb(34,34,34)"><font face="arial, sans-serif">University of California, Riverside</font></div><div style="color:rgb(34,34,34)"><font face="arial, sans-serif">UCI NIAMS P30 Skin Biology Center, <span>external member</span></font></div><div style="color:rgb(34,34,34)"><font face="arial, sans-serif">Website: <a href="https://sites.google.com/ucr.edu/qixuanwang/" style="color:rgb(17,85,204)" target="_blank">https://sites.google.com/ucr.edu/qixuanwang/</a></font></div></div></div></div>
