Txog tam sim no, cov tub ceev xwm tau mus rau qhov ntev heev los tsim cov phiaj xwm ntxuav thiab rov ua dua tshiab, raws li kev tshawb fawb tus kws sau ntawv, Kelly Lee. Tab sis cov kev ntsuas no tsis txaus, sau tseg rau tus kws tshaj lij, uas yog tus thawj coj ntawm Canada Research Chair hauv Kev Tswj Xyuas Kev Noj Qab Haus Huv Ntiaj Teb.
