Avoid diluting the impact of "chiefly interested in" by following it with a long list of secondary interests. Keep the primary focus clear and concise. For example, instead of saying "He is chiefly interested in astrophysics, but also dabbles in quantum mechanics and cosmology", state only the main interest unless the others are highly relevant.
