mongoose get data from find method and insert them in other schema

I am trying to build a web application.

At the website, I need to get instructor data from mongodb with mongoose and some of them will be inserted in other schema(Course).

if (!req.body) return console.log("No data sent");
    var newcourse;
    var iname = req.body.iname;
    var results;


/*ilist.find({ name: iname }).toArray((err, result) => {
    if (err) return console.log(err);
    results = result;
});*/
dbs.collection('instructors').find({ name: iname }).toArray((err, result) => {
    results = result;
    //console.log(result);        
});
// console.log(ilist.data);

newcourse = new clist({
    'coursename': req.body.coursename, 'coursenumber': req.body.coursenumber, 'coursecredit': req.body.coursecredit
    , 'courseroom': req.body.room, 'instructors.name': req.body.iname, 'instructors.email': results.email, 'instructors.phone': results.phone, 'instructors.role': req.body.role
});

newcourse.save(function (err) {
    if (err) {
        console.log(err);
        res.status(400);
        res.send(err);
    }
    else {
        res.status(200);
        console.log('A new course has been registered!');
        res.redirect('/course');
    }
});

-----schema-------------------

var instructorlist = mongoose.Schema({
    name: { type: String, required: true },
    age: { type: Number, required: true },
    gender: { type: String, required: true },
    DOB: { type: Date, required: true, default: Date.now },
    email: { type: String, required: true },
    phone: { type: Number, required: true },
    address: { type: String, required: true },
    dateofstart: { type: Date, required: true},
    courses: {
        coursename: { type: String, required: false },
        coursenumber: { type: Number, requird: false },
        coursecredit: { type: Number, required: false },
        courseroom: { type: String, required: false }
    }
});
var courselist = mongoose.Schema({
    coursename: { type: String, required: true },
    coursenumber: { type: String, required: true },
    coursecredit: { type: Number, required: true },
    courseroom: { type: String, required: false },
    courseregisteddate: {type: Date, default: Date.now},
    students: {
        name: { type: String, required: false },
        phone: { type: Number, requird: false },
        email: { type: String, required: false },
        class: { type: String, required: false }
    },
    instructors: {
        name: { type: String, required: false },
        phone: { type: Number, requird: false },
        email: { type: String, required: false },
        role: { type: String, required: false }
    }
});

I want to get instuctorlist's email and phone.(others are from req.body) and put it into newcourse variable for saving in mongodb. Thank you for reading it.
