Gerry Alanguilan is an architecture graduate from the University of Santo Tomas. Unsatisfied with the profession after working several years as a licensed architect, he became a comic book artist in 1992 after being inspired by Whilce Portacio, a fellow Filipino who was at the time drawing 'The X-men' for Marvel Comics. He left architecture completely to concentrate on his comics career, and after working in Philippine comics for several years, he was hired by Portacio when he formed a studio to produce work for American comic book companies.
He has since inked many comics over various pencillers including Portacio, Leinil Francis Yu, Gilbert Monsanto and Roy Allan Martinez. Among his credits are 'Stone', 'Wetworks', 'Grifter', 'Wolverine', 'X-Force, Darkness', 'Fantastic Four', 'Iron Man', 'Superman: Birthright', 'Batman/Danger Girl', 'High Roads' and 'Silent Dragon'. On the side, he has worked on various independent American companies where he could do his own pencilling in addition to inking. He has worked on 'Ochlocrat' and 'Taxman' for Comics Conspiracy, various adaptations of classic short stories for Graphic Classics including Bram Stoker's 'The Judges House', O Henry's 'The Furnished Room' and Rafael Sabatini's 'Plague of Ghosts'.
Alanguilan also tried to continue working on Philippine comics, where he could utilize his own writing and coloring on top of his illustrating. He has written and drawn 'Wasted' and 'Timawa' for Alamat Comics, 'Johnny Balbona' and 'Lastikman' for Mango Comics, short stories for 'Siglo: Freedom' and 'Siglo: Passion', and 'Humanis Rex!', appearing monthly in Fudge Magazine.
