If you are serious about mathematics and want to do more than mandatory courses, definitely go with her classes.","source_url":"https://www.ratemyprofessors.com/professor/1855980","quality_rating":5.0,"difficulty_rating":1.0},{"observed_at":"2026-09-07 16:05:34.119603+00:00","run_id":"20260907T155543-ce3781c4","source_review_id":"UmF0aW5nLTM2MzM4MjA1","source_instructor_id":"rmp:262518","instructor_name":"Sigurd Angenent","course_label":"math490","course_id":"MATH 490","course_uid":"course_b151d42dad875eb5e7e721b9","review_date":"2022-05-14 15:29:47 +0000 UTC","comment":"Sigurd is a very caring and inspirational professor for advanced math and research. His lectures are very concise and easy to follow. He always gives students an intuition how and why it works. I was in a research group on the curve shortening flow and the professor made the class very interesting. Highly recommended.","source_url":"https://www.ratemyprofessors.com/professor/262518","quality_rating":5.0,"difficulty_rating":4.0}]
