Eligibility Criteria:
Inclusion Criteria:~* Age ≥ 18 years and have had clinical type 1 diabetes for at least one year~* Diabetes managed using an insulin pump for ≥ 6 months~* Have used a CGM for at least one cumulative month over the last 12 months~* Prescription medication regimen stable for \> 1 month (except for medications that will not affect the safety of the study and are not expected to affect any outcome of the study, in the judgment of the principal investigator)~* Willing to remain within a 250 mile radius of MGH. No air travel will be allowed, and subjects will still be expected to follow the visit schedule as described.~* Willing to wear one Dexcom CGM sensor, and one leur-lock compatible infusion set that must be replaced every other day~* Have a mobile phone they will have access to at all times during the study for making contact with study staff~Exclusion Criteria:~* Unable to provide informed consent (e.g. impaired cognition or judgment)~* Unable to safely comply with study procedures and reporting requirements (e.g. impairment of vision or dexterity that prevents safe operation of the bionic pancreas, impaired memory, unable to speak and read English)~* Current participation in another diabetes-related clinical trial that, in the judgment of the principal investigator, will compromise the results of this study or the safety of the subject~* Pregnancy (positive urine HCG), breast feeding, plan to become pregnant in the immediate future, or sexually active without use of contraception Subjects must use acceptable contraception for the two weeks prior to the study, throughout the study and for the two weeks following the study.~Acceptable contraception methods include: Oral contraceptive pill (OCP), Intrauterine Device (IUD, hormonal or copper), Male condoms, Female condoms, Diaphragm or cervical cap with spermicide, Contraceptive patch (such as OrthoEvra), Contraceptive implant (such as Implanon, Nexplanon), Vaginal ring (such as NuvaRing), Progestin shot (such as Depo-Provera), Male partner with a vasectomy proven to be effective by semen analysis~* Current alcohol abuse (intake averaging \> 3 drinks daily in last 30 days) or other substance abuse (use within the last 6 months of controlled substances other than marijuana without a prescription)~* Unwilling or unable or to avoid use of drugs that may dull the sensorium, reduce sensitivity to symptoms of hypoglycemia, or hinder decision making during the period of participation in the study (use of beta blockers will be allowed as long as the dose is stable and the subject does not meet the criteria for hypoglycemia unawareness while taking that stable dose, but use of benzodiazepines or narcotics or other central nervous system depressants, even if by prescription, may be excluded according to the judgment of the principal investigator)~* Renal failure requiring dialysis~* Estimated Glomerular filtration rate \<15 mL/min/1.732~* Personal history of cystic fibrosis, severe pancreatitis, pancreatic tumor, pancreatectomy or any other pancreatic disease leading to diabetes mellitus.~* Any known history of coronary artery disease including, but not limited to, history of myocardial infarction, stress test showing ischemia, history of angina, or history of intervention such as coronary artery bypass grafting, percutaneous coronary intervention, or enzymatic lysis of a presumed coronary occlusion)~* Abnormal EKG consistent with coronary artery disease or increased risk of malignant arrhythmia including, but not limited to, evidence of active ischemia, prior myocardial infarction, proximal LAD critical stenosis (Wellen's sign), prolonged QT interval (\> 440 ms). Non-specific ST segment and T wave changes are not grounds for exclusion in the absence of symptoms or history of heart disease. A reassuring evaluation by a cardiologist after an abnormal EKG finding may allow participation.~* Congestive heart failure (established history of CHF, lower extremity edema, paroxysmal nocturnal dyspnea, or orthopnea)~* History of TIA or stroke15. Recent history of diabetic ketoacidosis (DKA) or severe hypoglycemia in the last 6 months. Severe hypoglycemia is defined as an event that required assistance of another person due to altered consciousness, and required another person to actively administer carbohydrate, glucagon, or other resuscitative actions. This means that the participant was impaired cognitively to the point that he/she was unable to treat himself/herself, was unable to verbalize his/ her needs, was incoherent, disoriented, and/or combative, or experienced seizure or coma.~* History of more than 1 episode of DKA requiring hospitalization in the last 2 years~* History of more than 1 episode of severe hypoglycemia in the last year.~* Untreated or inadequately treated mental illness (indicators would include symptoms such as psychosis, hallucinations, mania, and any psychiatric hospitalization in the last year), or treatment with anti-psychotic medications that are known to affect glucose regulation.~* Electrically powered implants (e.g. cochlear implants, neurostimulators) that might be susceptible to RF interference~* Unable to completely avoid acetaminophen for duration of study~* Established history of allergy or severe reaction to adhesive or tape that must be used in the study~* History of eating disorder within the last 2 years, such as anorexia, bulimia, or diabulemia or omission of insulin to manipulate weight~* History of intentional, inappropriate administration of insulin leading to severe hypoglycemia requiring treatment~* Use of oral (e.g. thiazolidinediones, biguanides, sulfonylureas, glitinides, DPP-4 inhibitors, SGLT-2 inhibitors) or non-insulin injectable (GLP-1 agonists, amylin) anti-diabetic medications~* Any diagnosed allergy to insulin lispro or insulin aspart~* Lives in or frequents areas with poor Verizon wireless network coverage (which would prevent study staff from contacting subjects)~* Any factors that, in the opinion of the principal investigator would interfere with the safe completion of the study
