Dr. Ichinose has a broad, innovative, and translational research focus on the organ protective roles of nitric oxide (NO) and hydrogen sulfide (H2S). He is an expert in cardiovascular physiology who has developed several unique experimental models that enable detailed characterization of organ dysfunction associated with critical illness.  He has created innovative models of several clinical conditions, including sepsis and post-cardiac arrest organ dysfunction.  Dr. Ichinose has discovered previously unrecognized protective roles for NO and H2S in major organs including the brain, heart, and liver. At MGH, he now directs a highly productive basic and translational resuscitation science laboratory. This combined basic science and clinical research program currently employs 10 research staff.
