No, he is not right. Some of the most outstanding scientists of our time are committed believers, and this has been true over the centuries. In fact, some say their Christian faith has made them better scientists, because they believed God has called them to explore His creation.
The real question is this: Is there a conflict between what the Bible teaches and what science says? The answer is no not when we understand them properly. Many years ago, I heard someone use a phrase that might help you: "All truth is God's truth." In other words, the truth God teaches us through His Word will never contradict the truth He teaches us through His world.
Never forget: God created everything that exists, including the laws that rule the universe. The Bible says, "In the beginning God created the heavens and the earth. ... God saw all that he had made, and it was very good" (Genesis 1:1, 31). If you become involved in medical research someday, you will only be uncovering what God has already done.
Commit your life into Christ's hands including your future. God made you, and He has a plan for your life, including your career. Don't be satisfied with anything less than His will. And if He does lead you into medical research, be grateful for the opportunities He will give you to make this world a better place.
