Albert J.R. Heck (born 25 November 1964) is a Dutch scientist and professor at Utrecht University, the Netherlands in the field of mass spectrometry and proteomics.

[18] The methods developed by Heck have been adopted by many scientists in other fields, to study how protein expression and phosphorylation are regulated in human cells and tissues by different biological processes and disease states.

[19][20] Additionally, he advocated the use of complementary proteases in shot-gun proteomics[21][22] and he introduced and developed novel peptide fragmentation strategies to elucidate site specific post-translational modifications.

[23] The latter improves determination of peptide and protein sequence information, which is particular helpful for the analysis of glycopeptides[24] and HLA antigens.

[37] The American Chemical Society honoured Albert Heck with the 'Frank H. Field and Joe L. Franklin Award for Outstanding Achievements in Mass Spectrometry' in 2015.

[38] In 2017, he was awarded the Spinoza Prize, the highest scientific distinction in the Netherlands for his "major contribution to the worldwide breakthrough of systematically mapping all proteins in human cells and their biological functions by means of mass spectrometry".
