אודות
ליאור גוטמן קיבל את הדוקטורט שלו מהאוניברסיטה העברית בירושלים.
הוא הצטרף לאוניברסיטת חיפה עם 20 שנות נסיון במחקר ופיתוח במחקר החקלאות הימית, כולל 12 שנים כחוקר ראשי במרכז הלאומי לחקלאות ימית של חקר ימים ואגמים לישראל, באילת.
המעבדה למיקרוביולוגיה ימית וביוטכנולוגיה בחקלאות ימית מתמקדת בתפקידים הקריטיים של חיידקים בסביבת החקלאות ימית במגוון תחומים כגון איכות מים, עיכול הזנה ובריאות. אנו חוקרים את הכוחות המשפיעים על הדינמיקה של אוכלוסיות מיקרואורגניזמים בסביבת הגידול והשפעתם על הביצועים, הבריאות והחוסן של האורגניזמים הרב-תאיים וסביבת הגידול וסביבת התרבות. המחקר מקיף מערכות חקלאות ימית שונות, כולל Integrated Multi-trophic Aquaculture (IMTA) ו Recirculating Aquaculture Systems (RAS), כמו גם מינים מגוונים כגון דגים, אצות, וקיפודי ים.
המחקר משלב מטגנומיקה מתקדמת וביואינפורמטיקה עם מיקרוביולוגיה קלאסית, כימיה וביולוגיה מולקולרית. זאת, לטובת פיתוח של יישומים בני קיימא להבטחת אריכות ימים של תעשיית החקלאות הימית ובטחון מזון וכן לפיתוח של פתרונות ויישומים ביוטכנולוגיים חדשניים המשלבים שימוש בחיידקים ימיים, גנים , אנזימים, וחומרי טבע שלהם.
ליאור נשוי ואב לחמישה ילדים. הוא אוהב לבלות זמן עם משפחתו, לשחות ולגלות את נפלאות עולם הטבע.
