ד"ר קויט סיים את הדוקטורט שלו בכימיה אורגנית בפיתוח אסטרטגיות שונות לסינתזה של מולקולות ופפטידים קטנים, בתמיסה ומצע מוצק, עבור יישומים טיפוליים שונים באוניברסיטה העברית. במחקר שלו התגבר על סינתזה מאתגרת, ופיתח פרוצדורה חדשנית ליצירת מעכבי אינטראקציות בין חלבונים. ד"ר קוויט זכה בפרס היוקרתי Kaye Innovation Award כאשר הפגין יצירתיות יוצאת דופן ככימאי מדיסינאלי   .medicinal chemist

בשנת 2008 הצטרף ד"ר קויט למחלקה Chemical and System Biology בבית הספר לרפואה באוניברסיטת סטנפורד. בסטנפורד התמקד בפיתוח כלים חדשים לוויסות אינטראקציות בין חלבונים. הוא היה המדען הראשון לפתח מעכב, אשר באופן סלקטיבי וויסת אינטראקציות בין קינאז לבין סובסרט אחד מתוך סובסרטים רבים.  כמו כן, הוא פיתח מעכב ספציפי של GTPase גדול, כדי לווסת את ביקוע המיטוכונדריה המוגזמת. מעכב זה פעיל מאוד במודלים של מחלות נוירודגנרטיביות. טכנולוגיה זו קיבלה רישיון לחברת ביופרמצבטיקה בישראל.
ד"ר קויט כיהן כיו"ר כנס במספר כנסים שונים, והיושב ראש הראשון של הכנס
